Due to the ongoing COVID-19 pandemic, the original program has been canceled. However, the program will be conducted through online lectures.

The existence of dark matter (DM) has been inferred from its gravitational interactions, yet the identity of the dark matter particles remains completely unknown. The dominant candidate for DM over the last 30 years has been Weakly Interacting Massive Particles (WIMPs). However, despite extensive underground (direct), telescope (indirect), and collider searches, dedicated experiments have not found any evidence of WIMPs. Meanwhile, several astrophysical small-scale structure and cosmological hints might be an indication that DM has non-gravitational interactions that cannot easily be explained with vanilla WIMPs.

This online workshop on the Less Travelled Path of Dark Matter (LTPDM) will bring together particle physicists and cosmologists from all over the world to address current trends in DM searches, focused on axions and primordial black holes, and map the way forward. The program will also include a school, with lectures addressed to students and postdocs, familiarizing them with new and advanced concepts.

We plan to have a longer physical workshop on dark matter, with a larger perspective, in the near future once the current global pandemic crisis has subsided.

This is an annual workshop on high energy theory held in Kyoto, Japan, but we have to shift it to online due to covid-19 this year. Each year, around 150 participants gather and there are around 40 short talks and 6 invited talks as well as poster sessions. This annual workshop is definitely one of the largest workshops of this field in Japan. The workshop covers various topics in string theory and quantum field theory such as the AdS/CFT correspondence, various dualities in string theories and gauge theories, exact results in supersymmetric gauge theories, entanglement entropy and its holographic description, string cosmology and phenomenology, and nonperturbative methods in quantum field theory.

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 subject of magnetic monopoles is by now classic in both physics and mathematics. Since intense advancements in mid 1970’s, numerous deep connections to theoretical physics, algebraic geometry, and geometric analysis have been discovered. Nonetheless, many important problems remain unsolved. Recently, monopoles acquired new significance in areas such as string theory, the Seiberg--Witten theory, quantum gauge-theory spaces of vacua, knot invariants, and the Geometric Langlands correspondence. This workshop brings together experts from around the world advancing very different perspectives, identify important open problems, and connecting diverse methods used by different groups.

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.

Neutrino physics is one of the most flourishing fields in particle physics. Neutrinos are elementary particles of nature, and scientists found they have mass. This was the topic of the 2015 Nobel prize, and is the only clear evidence for this mass beyond the Standard Model of particle physics. Scientists all over the world study properties of neutrinos or use neutrinos as a new tool to investigate astrophysical objects and fundamental properties of the universe. In this talk Dr Katori will review particle physics and the status of the most exciting neutrino projects in the world.

This event may also be delivered as an online webinar. If necessary due to Coronavirus or venue restrictions it will be an online webinar only.

New experiments are challenging our conventional understanding of past, present, and future in the quantum world. This workshop will, therefore, explore the very foundations of our understanding of space, time, and gravity by looking at new mathematical concepts and methods related to the quantum processes of measuring location, orientation, speed, cause and effect. We expect to forge a path that blends together new ideas on how our description of the structure of space and time must be modified to fully understand how to combine gravity with quantum physics.

Particle Physicists study matter at is smallest scale and try to reveal how the physical world is constructed from elementary particles and the forces acting between them. The well-known proton, neutron and similar particles are composed of quarks. Atoms also contain electrons; together with the two heavier versions of the electron (the muon and tau), each with its associated neutrino, they make up the group of leptons. Another ingredient of the catalogue of particles is the Higgs boson, discovered at the CERN Lab's Large Hadron Collider (LHC) in 2012.

The Particle Physics Community Planning Exercise (a.k.a. “Snowmass”) is organized by the Division of Particles and Fields (DPF) of the American Physical Society. Snowmass is a scientific study. It provides an opportunity for the entire particle physics community to come together to identify and document a scientific vision for the future of particle physics in the U.S. and its international partners. The P5 (Particle Physics Project Prioritization Panel) will take the scientific input from Snowmass and develop a strategic plan for U.S. particle physics that can be executed over a 10 year timescale, in the context of a 20-year global vision for the field.

The conference is jointly organized by TRIUMF (Vancouver, Canada) and Saint Mary’s University (Halifax, Canada).

The scientific program will be devoted to the latest experimental and theoretical developments in nucleus nucleus collisions with a wide range of topics.

An outstanding problem of modern physics is the reconciliation of the two most successful broad theories of physics: general relativity, which describes the gravitational force exerted by massive objects in terms of the bending and rippling of spacetime, and quantum mechanics, which describes the behavior of matter on the minute scales of subatomic particles such as electrons. While both theories are remarkably successful independently, they appear to give contradictory predictions of phenomena that involve gravity at the small scales at which quantum mechanics is relevant. Such phenomena include the Big Bang, when the universe was small enough to be described by quantum mechanics and sufficiently dense to also require a gravitational description; also the process of the final stages of the death of a large star, when a black hole is formed and the star’s matter is concentrated in an extremely small volume. A proper description of these phenomena requires a unified theory of quantum gravity.

Gravitational-waves are a new way to explore the sky and uncover the Universe’s deepest mysteries. Although the first detection of these "ripples of space-time" is only a few years old, scientists can now harness the potential of gravitational waves in testing Einstein’s General Relativity theory under extreme conditions, helping to understand the origin of matter, and measuring the evolution of the Universe. Researchers from all around the world are gathering in Oaxaca to discuss recent progress in, and the future of gravitational-wave science. The workshop "Detection and analysis of gravitational waves in the era of multi-messenger astronomy: From mathematical modelling to machine learning", provides a forum, unique in its genre, for discussing new mathematical methods in modelling, detecting, and analyzing gravitational waves, as well as their integration with machine learning, or artificial intelligence.
