What’s the Matter? A Cross-Frontier Pursuit of the Origin of Matter

22 Aug 2022, 09:00 → 2 Sept 2022, 16:00 Europe/Berlin

02.430 (Mainz Institute for Theoretical Physics, Johannes Gutenberg University)

Please note that the event has been shortened and will now end on September 2. Thank you.

Despite tremendous progress in particle physics in the last decades, the origin of matter remains an open mystery. At the heart of this mystery is the baryon asymmetry, produced during an unknown but consequential epoch of our cosmic history.

“What’s the matter?” brings together global experts from all subfields united by this problem to explore common and complementary opportunities for discovering the origin of matter. Topics include

• Theory frontier: improving computational techniques required to understand baryogenesis
• High-energy frontier: how can we test models of baryogenesis at current and future colliders, for instance by probing the physics leading to first-order phase transitions
• High-intensity and long-lifetime frontier: connections between baryogenesis and long-lived particles, and searches for the latter
• Precision and low-energy frontier: how can low-energy precision tests, in particular probes of CP violation, elucidate the physics of baryogenesis?
• Cosmology frontier: what traces can baryogenesis have left in the CMB, in gravitational waves, and in other cosmological observables?
• Neutrino frontier: the deep connections between neutrinos and baryogenesis – for instance in the context of leptogenesis – and experimental ways to probe it
• Dark matter frontier: what can dark matter tell us about the origin of baryons?
