Greg Landsberg: Searches for new physics with FACET - a Forward-Aperture CMS ExTension



In this talk, I'll discuss a new proposal for an extension of the CMS physics program at the HL LHC to look for light long-lived particles (such as ALPs, dark photons and Higgs bosons, Majorana neutrinos) in a FACET detector to be installed about 100 m downstream from the CMS interaction point. I'll discuss the vast physics landscape covered by FACET, a conceptual detector design, and first sensitivity studies showing that it has significantly extended sensitivity compared to the existing and proposed competing experiments.


Connections will begin at 12:30 with the seminar beginning at 13:00. Password for Zoom is NielsBohr.
