Baryon-number-violating nucleon decays into a dark photon particle
Jin-Han Liang, Yi Liao, Xiao-Dong Ma +1
Baryon-number-violating (BNV) nucleon decays into a light new particle represent an exciting yet experimentally unexplored frontier. In this work, we systematically study nucleon d…
Renormalization-group-improved constraints on dimension-7 baryon-number-violating operators
Yi Liao, Xiao-Dong Ma, Xiang Zhao
We study constraints on dimension-7 SMEFT baryon-number-violating operators from nucleon decays by incorporating full renormalization group (RG) running effects. At high new physic…
Comprehensive investigation of nucleon decays into one lepton plus two mesons
Wei-Qi Fan, Yi Liao, Xiao-Dong Ma
We systematically investigate baryon number violating (BNV) nucleon decays into one lepton () and two pseudoscalar mesons () within the low-energy ef…
Nucleon decays into three leptons: contact contributions
Yi Liao, Xiao-Dong Ma, Xiang Zhao
Baryon number violating (BNV) nucleon decays into three leptons provide a unique probe of BNV interactions beyond the conventional two-body modes involving a single lepton and a li…
Nucleon decays into three leptons: Noncontact contributions
Jing Chen, Yi Liao, Xiao-Dong Ma +1
We investigate baryon number violating (BNV) nucleon decays into three leptons from noncontact contributions that are induced by dimension-6 (dim-6) BNV operators in low-energy eff…
Light fermionic dark matter window in the scotogenic inverse seesaw model
Huan-Can Liang, Yi Liao, Xiao-Dong Ma +2
The origin of neutrino mass and the nature of dark matter (DM) remain unresolved puzzles in particle physics, and an appealing possibility is to address both in a unified picture.…
