Meetings/Workshops on High Energy Physics, Particles and Fields in Italy

The Galileo Galilei Institute for Theoretical Physics

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

Theory in Trona (TinT), the first international school on theoretical physics will take place in Gerola Alta at the Rifugio Trona-Soliva. The school is intended for PhD students and young postdocs working on string theory, supersymmetry and supergravity.

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.

Binary Star Mergers - the observations of gravitational waves, Binary Star Mergers – simulations, Binary Star Mergers – nucleosynthesis, Direct and indirect Dark Matter Searches, Axions - Dark Matter?, Dark Matter Searches at the LHC, Neutrino Mass from Tritium Decay, Neutrinoless Double Beta Decay (Majorana versus Dirac Neutrino), Neutrino Mass from electron Capture, Elastic Neutrino scattering – COHERENT, The Reactor Neutrino Spectrum Anomaly, Search for the Cosmic Neutrino Background, Neutrinos and Cosmology

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.

1. Supersymmetry and supergravity: motivations and developments, 2. Formal analogies in/between particle physics, condensed matter physics, and cosmology, 3. Computer simulation in theoretical high energy physics and in cosmology, 4. The interplay of experimental results and BSM model-building

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.

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.

Topological properties of gauge theories find application in the characterization of novel phases of matter and in establishing nonperturbative phenomena such as the duality relations between quantum field theories in three and four spacetime dimensions. This conference is meant to expose the current status of research in several domains dealing with topology and duality
