Revisiting $B_{c}^{-} \to J / ψ (η_{c}) L^{-}$ decays within the SM and beyond in QCD factorization

Wei-Jun Deng, Fang-Min Cai, Xin-Qiang Li +2

Motivated by the deviations observed between the data and the SM predictions of $B (B ˉ_{s}^{0} \to D_{s}^{+} π^{-})$ and $B (B ˉ_{d}^{0} \to D^{+} K^{-})$ , we revisit the $B…

CP asymmetries of $t \to c γ$ and $t \to c g$ decays in the aligned two-Higgs-doublet model

Fang-Min Cai, Rui-Lin Fan, Xin-Qiang Li +1

We study the CP asymmetries of the rare top-quark decays $t \to c γ$ and $t \to c g$ in the aligned two-Higgs-doublet model (A2HDM), which is generically characterized by new source…

STCF Conceptual Design Report: Volume 1 -- Physics & Detector

M. Achasov, X. C. Ai, R. Aliberti +424

The Super $τ$ -Charm facility (STCF) is an electron-positron collider proposed by the Chinese particle physics community. It is designed to operate in a center-of-mass energy range…
