TPPC weekly seminar (remote): Matheus Hostert - "Semi-Visible Dark Photons"

Wednesday 16 Nov 2022, 12:30 → 14:00 Europe/London

Strand Building, S7.06

Speaker: Matheus Hostert, Perimeter Institute

Title: Semi-Visible Dark Photons

Abstract: A kinetically mixed dark photon is a broadly-encompassing extension of the Standard Model. It is also conceivable that if it exists, it would be a portal to one or multiple generations of dark fermions. In this talk, I will discuss some lamppost models where MeV to GeV dark photons lead to a new sector of unstable fermions, with or without dark matter candidates. I will focus on their semi-visible signatures (visible + missing energy) at e+e− colliders and neutrino detectors. We will see that some of these models can still account for the discrepancy in the muon g-2 and are easily testable in current experiments.
