Axion-like Dark Matter from the Type-II Seesaw Mechanism

Wei Chao, Mingjie Jin, Hai-Jun Li +1

Although axion-like particles (ALPs) are popular dark matter candidates, their mass generation mechanisms as well as cosmic thermal evolutions are still unclear. In this letter, we…

Direct detection of Sub-GeV Dark Matter via 3-body Inelastic Scattering Process

Wei Chao, Mingjie Jin, Ying-Quan Peng

Direct detection of Sub-GeV dark matter (DM) is challenging because the recoil energy of the nuclei or electron from the elastic scattering of a sub-GeV DM off the target can hardl…

Study of semileptonic decay of $B ˉ_{s}^{0} \to ϕ l^{+} l^{-}$ in QCD sum rule

Ying-Quan Peng, Mao-Zhi Yang

In this work we study the semi-leptonic decay of $B ˉ_{s}^{0} \to ϕ l^{+} l^{-}$ ( $l = e, μ, τ$ ) with QCD sum rule method. We calculate the $B ˉ_{s}^{0} \to ϕ$ translation form factors relev…

Form Factors and Decay of $B ˉ_{s}^{0} \to J / ψ ϕ$ From QCD Sum Rule

Ying-Quan Peng, Mao-Zhi Yang

We calculate $B ˉ_{s}^{0} \to ϕ$ translation form factors $V$ , $A_{0}$ , $A_{1}$ , $A_{2}$ based on QCD sum rule and study the nonleptonic two-body decay of $B ˉ_{s}^{0} \to J / ψ ϕ$ with the f…

SU(2) finite temperature phase transition and Michael sum rules

Yingcai Peng, Richard W. Haymaker

We studied the finite temperature phase transition of SU(2) gauge theory on four-dimensional Euclidean lattices by Monte Carlo simulations, and measured the flux distributions of a…
