Phenomenological study of diquark effects in $B ˉ_{(s)}^{0} \to D_{(s)}^{(*) +} L^{-}$ decays

Fang-Min Cai, Xin-Qiang Li, Tong-Kai Liu +2

Motivated by the deviations between experimental data and SM predictions for the branching fractions of $B ˉ_{(s)}^{0} \to D_{(s)}^{(*) +} L^{-}$ decays with $L = π, K^{(*)}, ρ$ , we in…

$∣ V_{c b} ∣$ determinations from $B ˉ \to D^{(*)} ℓ ν ˉ$ decays within the SM and beyond

Wen-Sheng Fang, Syuhei Iguro, Xin-Qiang Li +3

We investigate the $∣ V_{c b} ∣$ determinations from exclusive semi-leptonic $B ˉ \to D^{(*)} ℓ ν ˉ$ decays, together with comprehensive Bayesian fit analyses of the $\bar{B} \…

Probing TeV-Scale Inverse-Seesaw Leptogenesis and Majorana Dark Matter in $U (1)_{B - L}$ Models at Multi-TeV Muon Colliders

Xin-Qiang Li, Himadri Roy, Tripurari Srivastava +2

We investigate a predictive and testable framework in which dark matter (DM), heavy-neutrino dynamics, and the BAU originate from correlated interactions within a local $U(1)_{B-L}…

$B ˉ_{s, d}^{0} \to J / ψ μ^{+} μ^{-}$ 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…
