HEP Seminar – Fall 2019 -Seto

December 9, 2019 @ 4:00 pm - 5:00 pm

Speaker: Prof. Osamu Seto (Hokkaido University)

Title: Electric dipole moments and Higgs funnel annihilating dark matter
in CPV MSSM

Abstract: We investigate electric dipole moments (EDMs) in a CP-violating minimal
supersymmetric standard model with the Bino-like neutralino dark matter
(DM) annihilating through the heavy Higgs funnel. We show that
CP-violating phases of a few degrees in gaugino and Higgsino mass
parameters are consistent with the current bound by EDMs of the
electron, the neutron, and the mercury. We also show that effects of
CP-violating phases induce a difference in DM-nucleon scattering cross
section by a factor.
