Constraints on Pseudo-Nambu-Goldstone dark matter from direct detection experiment and neutron star reheating temperature
Y. Zeng, Xiang Xiao, Wei Wang
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.
