$∣ V_{c b} ∣$ determinations from $B ˉ \to D^{(*)} ℓ I^ˉ ½$ 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 $B ˉ \to D^{(*)} ℓ I^ˉ ½$ decays, together with comprehensive fit analyses of the $\bar{B} \to D^{(*…

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}…

$B ˉ_{s, d}^{0} \to J / I ¨ I^¼^{+} I^¼^{-}$ Decays in QCD Factorization

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

Motivated by the first LHCb searches for the rare $B ˉ_{s, d}^{0} \to J / I ¨ I^¼^{+} I^¼^{-}$ decays, we perform a detailed study of these processes within the QCD factorization forma…

On sum rules for semi-leptonic $b \to c$ and $b \to u$ decays

Wen-Feng Duan, Syuhei Iguro, Xin-Qiang Li +2

The semi-leptonic $b \to c l I^½$ processes are receiving a lot of attention, as the lepton flavor universality violation has been hinted by the measured ratios $R_{D^{(*)}} = Î(B…

Revisiting $B_{c}^{-} \to J / I ¨ (I^\cdot_{c}) L^{-}$ 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 $B (B ˉ_{s}^{0} \to D_{s}^{+} I ¨ ^{-})$ and $B (B ˉ_{d}^{0} \to D^{+} K^{-})$ , we revisit the $…

Rare $W \to B_{c} + I^^{3}$ 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…
