Abstract:

Pseudo-Nambu-Goldstone dark matter can interact with Standard Model fermion through the Higgs portal, and some models can emerge a cancellation mechanism that helps to escape the stringent constraints from direct detection experiments. In this paper we explore new constraints of these cancellation models on parameter space of non-zero momentum transfer, from both the current direct detection experiment and the neutron star temperature via the dark matter reheating mechanism.

Biography:

Yu-Pan Zeng is a PhD candidate at Sun Yat-sen University in School of Physics. His research focuses on phenomenology study of Dark Matter(DM). Besides DM relic density, his works mainly use collider and direct detection to give constraints on DM model. His interests also include building.
