Lepton flavor of four-fermion operator and fermion portal dark matter

Yuxuan He, Gang Li, Jia Liu +2

We study the ultraviolet realization of semileptonic four-fermion operator $O_{l e d q}^{I^\pm I^^{2} 11}$ that incorporates Majorana dark matter (DM) in both lepton-flavor-conserving (LFC) an…

Valence Quark Distributions in Pions: Insights from Tsallis Entropy

Jingxuan Chen, Xiaopeng Wang, Yanbing Cai +2

We investigate the valence quark distributions of pions at a low initial scale ( $Q_{0}^{2}$ ) by employing Tsallis entropy, a non-extensive measure that effectively captures long-range…

Relativistic corrections to double $B_{c}$ meson production in $e^{+} e^{-}$ annihilation

Xiao-Peng Wang, Yi-Jie Li, Guang-Zhi Xu +1

Within the framework of nonrelativistic QCD (NRQCD) factorization, we investigate the relativistic corrections to the production of double $B_{c}$ mesons in $e^{+} e^{-}$ annihilation. Th…
