Cosmological Probes of New Physics @ UMD

15 Sept 2022, 09:00 → 17 Sept 2022, 13:15 US/Eastern

PSC 3150 (University of Maryland)

Kaustubh Agashe (University of Maryland), Zackaria Chacko (University of Maryland), Anson Hook (University of Maryland), Rabi Mohapatra (University of Maryland), Raman Sundrum (University of Maryland), Gustavo Marques Tavares (University of Maryland), Yuhsin Tsai (University of Maryland), Manuel Alejandro Buen Abad Najar

Maryland Center for Fundamental Physics (MCFP), at University of Maryland,  is proud to host a three-day workshop on Cosmological Probes of New Physics. The workshop will bring together particle physicists and cosmologists to share new ideas of using cosmological data, in particular CMB, LSS, BAO, gravitational waves and future 21 cm measurements, to search for new physics. Topics include, but are not limited to, the cosmological signals of dark sectors, neutrino cosmology, the inflationary/reheating mechanism, cosmological collider physics, and the H0 problem.

Due to space constraints, participation at the conference is by invitation only.
