NPAC (Nuclear/Particle/Astro/Cosmo) Forum
Dark Matter from Weak Polyplets
Time: 2:30 pm
Place: 4274 Chamberlin
Speaker: Jennifer Kile, Northwestern University
Abstract: We investigate the possibility of new fermion multiplets charged under the Standard Model gauge group, with the aim of obtaining a possible dark matter candidate. These new fermions are charged under SU(2)xU(1); their quantum numbers are determined by requiring anomaly cancellation and insisting that all new particles become massive via Yukawa couplings with the SM Higgs boson. Constraints from colliders, electroweak precision measurements, and DM direct detection are considered; we find that this model can accommodate a viable DM candidate.
