Windows into New Physics in the Sky

14 Jul 2025, 09:00 → 1 Aug 2025, 16:00 Europe/Berlin

2413/2-430 - MITP Seminar Room (MITP - Mainz Institute for Theoretical Physics, Johannes Gutenberg University Mainz)

Registration closed on 15 April 2025 (11:59 pm CET). 

The workshop will focus on cosmological and astrophysical “windows” on BSM physics. Our goal will be to bring together experts from different areas of particle phenomenology, cosmology and astroparticle physics, to answer our guiding questions: What can we learn on new physics from upcoming experiments and observations, ranging from table-top to cosmology? And what are the predictions of new BSM scenarios that we may try to test in the future? Key topics that will be discussed include gravitational wave observations and implications for fundamental physics, new Dark Matter candidates and detection strategies, early Universe dynamics and cosmological surveys. 

This workshop will bring together leading experts from each community, who will share their newest insights with lots of free time to discuss. It will therefore serve as a collaborative platform, facilitating the exchange of insights and advancements in key areas of particle physics research, and act as a nexus for interdisciplinary collaboration. Participants will have the opportunity to engage with the latest tools, models, and methodologies from diverse fields, creating an environment conducive to the flourishing of new ideas.
