Are the new particles heavy or light in $b \to s E_{miss}$ ?

Quan-Yi Hu

In this work, we study the $B^{+} \to K^{+} E_{miss}$ , $B^{0} \to K^{* 0} E_{miss}$ , and $Λ_{b}^{0} \to Λ^{0} E_{miss}$ decays under three different new physics hypothes…

New physics in the angular distribution of $B_{c}^{-} \to J / ψ (\to μ^{+} μ^{-}) τ^{-} (\to π^{-} ν_{τ}) ν ˉ_{τ}$ decay

Quan-Yi Hu, Xin-Qiang Li, Xiao-Long Mu +2

In $B_{c}^{-} \to J / ψ (\to μ^{+} μ^{-}) τ^{-} ν ˉ_{τ}$ decay, the three-momentum $p_{τ^{-}}$ cannot be determined accurately due to the decay products of $τ^{-}$ inevitably include an…

The measurable angular distribution of $Λ_{b}^{0} \to Λ_{c}^{+} (\to Λ^{0} π^{+}) τ^{-} (\to π^{-} ν_{τ}) ν ˉ_{τ}$ decay

Quan-Yi Hu, Xin-Qiang Li, Ya-Dong Yang +1

In $Λ_{b}^{0} \to Λ_{c}^{+} (\to Λ^{0} π^{+}) τ^{-} ν ˉ_{τ}$ decay, the solid angle of the final-state particle $τ^{-}$ cannot be determined precisely since the decay products of the $τ^{-}$ include…

Probing new physics in semileptonic $Σ_{b}$ and $Ω_{b}$ decays

Jin-Huan Sheng, Jie Zhu, Xiao-Nan Li +2

Recently, several hints of lepton non-universality have been observed in the semileptonic B meson decays in terms of both in the neutral current ( $b \to s l l ˉ$ ) and charged cu…

Revisiting the $B$ -physics anomalies in $R$ -parity violating MSSM

Quan-Yi Hu, Ya-Dong Yang, Min-Di Zheng

In recent years, several deviations from the Standard Model predictions in semileptonic decays of $B$ -meson might suggest the existence of new physics which would break the lepton-…

Explaining $b \to s ℓ^{+} ℓ^{-}$ data by sneutrinos in the $R$ -parity violating MSSM

Quan-Yi Hu, Lin-Lin Huang

The recent measurements on $b \to s ℓ^{+} ℓ^{-}$ processes suggest the existence of lepton-flavour-universality breaking new physics. In this work, we have explored the possibilit…

$B_{s (d)} - B ˉ_{s (d)}$ Mixing and $B_{s} \to μ^{+} μ^{-}$ Decay in the NMSSM with the Flavour Expansion Theorem

Quan-Yi Hu, Xin-Qiang Li, Ya-Dong Yang +1

In this paper, motivated by the observation that the Standard Model predictions are now above the experimental data for the mass difference $Δ M_{s (d)}$ , we perform a detailed study…

$b \to c τ ν$ Transitions in the Standard Model Effective Field Theory

Quan-Yi Hu, Xin-Qiang Li, Ya-Dong Yang

The $R (D^{(*)})$ anomalies observed in $B \to D^{(*)} τ ν$ decays have attracted much attention in recent years. In this paper, we study the $B \to D^{(*)} τ ν$ , $Λ_{b} \to Λ_{c} τ ν$ ,…

R-parity violating solutions to the $R_{D^{(*)}}$ anomaly and their GUT-scale unifications

Quan-Yi Hu, Xin-Qiang Li, Yu Muramatsu +1

Recently, several $B$ -physics experiments report interesting anomalies in the semi-leptonic decays of $B$ -mesons, such as the excess in the $R_{D^{(*)}}$ measurements. These ano…

The $Λ_{b} \to Λ (\to p π^{-}) μ^{+} μ^{-}$ decay in the aligned two-Higgs-doublet model

Quan-Yi Hu, Xin-Qiang Li, Ya-Dong Yang

The rare baryonic decay $Λ_{b} \to Λ (\to p π^{-}) μ^{+} μ^{-}$ provides valuable complementary information compared to the corresponding mesonic $b \to s μ^{+} μ^{-}$ transition. In this paper, using…

$B^{0} \to K^{* 0} μ^{+} μ^{-}$ Decay in the Aligned Two-Higgs-Doublet Model

Quan-Yi Hu, Xin-Qiang Li, Ya-Dong Yang

In the aligned two-Higgs-doublet model, we perform a complete one-loop computation of the short-distance Wilson coefficients $C_{7, 9, 10}^{(')}$ , which are the most relevant on…
