Two Component Higgs-Portal Dark Matter
Ligong Bian, Ran Ding, Bin Zhu
In this paper, we construct two component dark matter model and revisit fine-tuning, unitarity and vacuum stability problem in this framework. Through Higgs-portal interactions, th…
Supersymmetry Breaking in Anti-de Sitter spacetime
Bin Zhu, Kun Meng, Ran Ding
We study the questions of how supersymmetry is spontaneously broken in Anti de-Sitter spacetime. We verify that the would-be R-symmetry in plays a central role for the exis…
Comprehensive Constraints on a Spin-3/2 Singlet Particle as a Dark Matter Candidate
Ran Ding, Yi Liao, Ji-Yuan Liu +1
We consider the proposal that dark matter (DM) is composed of a spin-3/2 particle that is a singlet of the standard model (SM). Its leading effective interactions with ordinary mat…
Singlet-Assisted Supersymmetry Breaking For Theories
Bin Zhu, Kun Meng, Ran Ding +1
We investigate local supersymmetry-breaking vacua in s-confining theories with gauge group . By adapting the general recipe developed by Shadmi and Shirman, we construct a…
