The phenomenon of the axion kinetic misalignment with a generic PQ-breaking operator
Xiangwei Yin, Ligong Bian
We investigate the phenomenology induced by generic PQ-breaking operators within the axion kinetic misalignment framework. We analyze their impact on the relic density of axion dar…
The nano-hertz and milli-hertz stochastic gravitational waves in the minimal clockwork axion model
Xiangwei Yin, Cheng-Wei Chiang, Bo-Qiang Lu +1
The clockwork framework can realize TeV-scale symmetry breaking while generating a large axion decay constant \(f_a\). We propose a minimal clockwork axion model with t…
Light right-handed Smuons at the LHC: Natural dark matter and in an unexplored realm of the pMSSM
Xiangwei Yin, Tianjun Li, James A. Maxin +1
We introduce an in-depth study of an unprobed pMSSM region offering a natural solution to dark matter. Since the 1980s this region has been referred to as the "bulk", consisting of…
The Right-Handed Slepton Bulk Region for Dark Matter in Generalized No-scale - with Effective Super-Natural Supersymmetry
Xiangwei Yin, James A. Maxin, Dimitri V. Nanopoulos +1
We propose Generalized No-Scale Supergravity, the simplest scenario for Effective Super-Natural Supersymmetry, naturally solving the supersymmetry electroweak fine-tuning problem a…
