The origin of dark matter (DM) is among the most urgent questions in fundamental physics, as astronomical observations do not inform us directly about its particle nature. The proposed workshop will bring together theorists and experimentalists to explore new theoretical avenues and detection strategies. During the workshop we will focus on well-motivated and long-standing theories of DM, such as WIMPs and axions, and we will assess the status of fast-moving current searches. We will identify new DM theories, with particular emphasis on those giving distinct predictions from WIMPs. There will also be extensive discussions about new ideas for discovering DM through direct detection, indirect detection, collider production, and cosmological observations. Finally, we will explore dark-sector extensions of the standard model, which can yield distinctive cosmological and astrophysical signals, as well as exotic events at colliders.

Week 1: New theories and the dark matter mass landscape, Week 2: Direct searches, Week 3: Indirect and astrophysical probes, Week 4: Searches at accelerators, Week 5: One week conference covering the themes of the workshop, Week 6: Axions and ALPs, Week 7: Primordial black holes dark matter and gravitational waves

The purpose of the meeting is to bring together experts and young researchers in the areas of nuclear, particle and astro-physics as well as cosmology and the pertinent interrelations among these fields. The aim is to discuss the current status of the field and to explore future directions, both in experiment and theory. With the recent observation of gravitational-wave signals of black-hole and neutron-star mergers - for the latter in coincidence with electromagnetic signals -, the meeting is particularly timely. The aim is to cover a broad range of topics to elucidate synergies and identify areas of future progress. This should be especially beneficial to the younger participants of the meeting.

The bi-annual 12th International Workshop COOL'19 will be held on September 23 - 27, 2019, and co-hosted by the Budker Institute of Nuclear Physics SB RAS and Novosibirsk State University. The workshop will be focused on the various aspects of the cooling methods and technics of charged particles.

Along with the direct searches of new particles at the LHC, low-energy phenomenology offers many complementary ways to search for physics beyond the Standard Model. The low-energy searches, however, are often hindered by the insufficiently precise knowledge of hadronic contributions. The last decade has witnessed tremendous progress towards ab-initio and model-independent determinations of these contributions. The purpose of this meeting is to cross-examine the empirical and theoretical progress in this field and the implications in beyond-the-SM physics.

The Swampland program gives general constraints on effective theories to be compatible with quantum gravity, which defines the Landscape of consistent theories, and is quickly gaining command of the fundamental understanding of open questions in particle physics and cosmology, ranging from the hierarchy of fundamental scales in nature, to the origin and final fate of the universe. Current research surfs over several powerful conjectures, whose riptide deposits valuable implications on the structure of effective theories, their spectrum of particles, their moduli spaces and potentials. Time is ripe to navigate the swampland, collecting these results and conjectures, and weaving them up to unveil fundamental structures in quantum gravitational theories. This workshop plans to gather the leading experts in the field to review our knowledge on the Swampland extension, the underlying related fundamental questions within quantum gravity and string theory as well as possible constraints for particle physics and cosmology.

The mathematical problem we plan to tackle takes its source in questions concerning graphene and the estimate of energy gaps. The model we study is a two dimensional massless Dirac operator on a regular bounded domain. We are interested in estimating the asymptotic of the gap at zero. More precisely, we want to derive the asymptotics for large magnetic field of the first negative eigenvalue and the first positive eigenvalue.

RESEARCH IN PAIRS

The Galileo Galilei Institute for Theoretical Physics

Ever since the Standard Model was established, there have been speculations about physics “beyond the Standard Model” (BSM), giving rise to a steady flow of models of “new physics” and letting the borders between high energy physics, astrophysics, and cosmology become increasingly permeable. So far, though, experiments failed to provide evidence for new physics, generating increasing talk of a “crisis” of these research programs, calling into question their premises, such as the principle of naturalness, or even questioning their scientific methodology. The workshop aims at approaching the present situation from a historical-critical perspective, contextualizing and questioning the developments of earlier decades, both to understand better their past and present scope, and to provide new material for reflections on contemporary physical research.

The symposium aims at bringing together experts on the topics of variational and nonperturbative methods in quantum field theory, topological and conformal field theory, and quantum entanglement in QFT. Those topics have recently experienced a revival of interest due to advances made in the field of quantum computing and quantum entanglement theory. Area laws and entanglement Hamiltonians have opened up a new window into the structure of quantum correlations in strongly correlated systems, and led to a revisit of the variational principle for quantum field theories in the form of quantum tensor networks. Dualities, as symbolized in the picture of Magritte above, and nonlocal symmetries are proving to be manifestations of emerging order in the entanglement structure, and tensor networks provide representations for the underlying tensor fusion categories. The main purpose of this conference is to bring together the different communities that have been working on the many theoretical aspects of this program.

This meeting is the 7th thematic workshop on Baryon and Lepton Number Violation that takes place every two years. This edition will take place at the Institute of Theoretical Physics IFT in Madrid, on 27-30 May 2019.

The Conference on Quantum gases, fundamental interactions and cosmology- Second Edition (QFC 2019) will be held in Pisa from 23 to 26 October 2019. Aim of the conference is to bring together scientists in both experimental and theoretical physics from the fields of ultracold quantum gases, fundamental interactions, and cosmology, with the aim of sharing and brainstorming on challenging open common problems, which can be zoomed in and out via a cross-disciplinary approach.

After QFC 2017, the Conference will be in its each second edition of a series of appointments to be held each second year.

The mutual frontiers among these three apparently separated disciplines have been recently blossoming with new innovative, cutting edge research. To the well-established connections between cosmology and high-energy physics, current bright examples are the research activities in analogue gravity and superfluid analogies of cosmological phenomena, and of quantum simulations of lattice gauge theories using ultracold atoms in optical lattices. We intend to use this momentum and opportunities to establish strong collaborations among participants and leading groups to open new pathways leading to breakthrough results, in this spirit, the keynote speakers of the first edition, QFC2017, have been invited and have joined the Scientific Advisory Board.

REF 2019 is the 6th workshop in the series of workshops on Resummation, Evolution, Factorization. It aims to bring together experts who deal with high-energy hadronic processes where the transverse momentum of the involved partons plays a relevant role. This includes researchers of different communities specialized in, e.g., nucleon structure, transverse-momentum-dependent functions, small-x physics, jet physics, heavy-quark production, multi-parton interactions, etc. Factorization theorems and resummation of large logarithms through evolution equations are key concepts for all these communities, which address overlapping physical phenomena with however different languages, calling for mutual understanding. Indeed, the REF series of workshops aims at bridging the gap among them, to promote development and potential synergies, in view of the wealth of data taken at facilities like the LHC, RHIC or JLab, and future planned ones like the EIC.

Non-vanishing neutrino masses and the existence of non-baryonic Dark Matter (DM) represent the only two firm observational evidences of new physics beyond the Standard Model (SM). Proposed neutrino species can also in principle constitute the bulk of the dark matter. They may moreover leave different signatures on astrophysical scales than the hitherto standard WIMP-based cold dark matter. As the parameter space for the latter is increasingly constrained experimentally, such alternates become more relevant, along with others such as the lately topical ultra-light axions.

The NDM-2020 aims to be a forum for the discussion and exchange of ideas regarding the particle phenomenology, astrophysical signatures and experimental constraints related to those two fundamental and actively studied issues in particle and astroparticle physics, namely neutrinos and dark matter, and their possible connections.

Long-standing conference bringing together researchers and students from various fields of subatomic physics. The conference location is Bormio, a beautiful mountain resort in the Italian Alps.

This conference will bring together experts in cosmology, particle physics, and fundamental theory to address how and when the universe thermalizes following inflation, and the associated particle physics and dark matter phenomenology. Important topics that will be covered include hidden sector model building in the LHC era, thermalization of the universe following inflation, possibilities of post-inflation cosmic history prior to nucleosynthesis, and associated experimental signatures. The conference aims to attract researchers in different areas to develop new directions in model building and establish new experimental paths for probing early universe cosmology and dark matter phenomenology.

Many remarkable properties of gauge theories rely on the topology of field configurations and/or ambient spacetime and are connected with quantum anomalies and nonperturbative excitations. These properties, often exact, have many implications in the physics of fundamental interactions, condensed matter systems and statistical mechanics models. They also account for a large part of the investigations in string theory, and combined with supersymmetry have led to exact solutions of low-energy theories and the discovery of duality relations between supersymmetric gauge theories. Meanwhile, a renewed interest in topological aspects has emerged from condensed matter physics, through the study of topological phases of quantum matter. The effective field theories for these systems are not of the usual Landau-Ginzburg-Higgs type, rather, they are described by topological gauge theories. The goal of this GGI activity is to bring together theoreticians of different backgrounds, in condensed matter, high energy and mathematical physics, with the belief that interdisciplinary approaches can lead to substantial progress in many directions.

In the last decade a number of experimental and theoretical discoveries have caused a notable revival of interest in systems with large local Hilbert spaces which realize a variety of intriguing and largely unexplored phenomena such as non-Fermi-liquid behavior, exotic quantum criticality, orbitally selective Mott physics, multipolar/hidden orders and more. While many models have been proposed for each of these phenomena, a single framework to understand the systems with multiple degrees of freedom and, consequently, richer order parameters and richer quasiparticles, is missing.

Modularity is at the heart of many deep results in mathematics--from the proof of Fermat’s last theorem to moonshine to the Langlands correspondence. At the same time, modular group representations and automorphic forms underlie many interesting physical phenomena in quantum field theory and string theory, including understanding of dualities, boundary conditions, and supersymmetric black holes, among other things. This conference will bring together physicists and mathematicians to discuss emerging connections between a web of fundamental objects in physics and mathematics, united in the crucial role played by modularity.

The Large Hadron Collider (LHC) is the world’s facility for probing fundamental physics at the electroweak scale and well beyond. As it enters a new phase of extended data accumulation, two broad challenges emerge: how to fulfill the potential for percent-level precision with the large dataset, and how to maximise the information that can be extracted from each event about the underlying scattering process, in particular with machine learning. Solving these problems will have an impact across a wide range of physics topics: establishing the properties of the newly discovered interactions of the Higgs sector and understanding electroweak symmetry breaking, enhancing the sensitivity of searches for physics beyond the Standard Model (BSM), and precision measurements of a range of fundamental parameters in the Standard Model.
