$B ˉ_{s, d}^{0} \to J / ψ μ^{+} μ^{-}$ Decays in QCD Factorization

Xin-Qiang Li, Yan Shi, Ya-Dong Yang +2

Motivated by the first LHCb searches for the rare $B ˉ_{s, d}^{0} \to J / ψ μ^{+} μ^{-}$ decays, we perform a detailed study of these processes within the QCD factorization formalis…

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…

Rare $W \to B_{c} + γ$ decay up to the NNLO and NLL accuracy in QCD

Xin-Qiang Li, Ya-Dong Yang, Yu-Dong Zhang +1

We perform a detailed theoretical study of the rare radiative decay of the $W$ boson into a $B_{c}$ meson and an on-shell photon. The decay amplitude is described by two independent…

Phenomenological anatomy of top-quark FCNCs induced by a light scalar singlet

Biao-Feng Hou, Xin-Qiang Li, Ya-Dong Yang +2

Scalar singlets under the Standard Model gauge group appear naturally in many well-motivated New Physics scenarios, such as the composite Higgs models. Unlike the Higgs boson in th…
