Abstract Recently, the Belle II collaboration announced the first measurement of the branching ratio B B + → K + ν ν ¯ $$ \mathcal{B}\left({B}^{+}\to {K}^{+}\nu \overline{\nu}\right) $$ , which is found to be about 2.7σ higher than the Standard

Motivated by the latest CDF W-mass measurement as well as the muon g−2 anomaly and the discrepancies observed in b→sℓ+ℓ− transitions, we propose an extension of the Standard Model (SM) with the SU(2)L-singlet vector-like fermion partners th

The recently updated measurement of the W-boson mass by the CDF collaboration exhibits a 7σ deviation from the SM expectation, which may imply a sign of new physics beyond the SM. The observed discrepancy could be explained by new fermions that carr

Motivated by the recent anomalies in b→sℓ+ℓ− transitions, we explore a minimal Z′ scenario, in which the Z′ boson has a flavour-changing coupling to charm and top quarks and a flavour-conserving coupling to muons. It is found that such a

Abstract Motivated by the recent LHC data on the lepton-flavor violating (LFV) decays h → ℓ 1 ℓ 2 and B s,d → ℓ 1 ℓ 2, we study the Higgs-mediated flavor-changing neutral current (FCNC) interactions in the effective field theory (EFT) app

Loop-induced Hgg and Hγγ coupling play an important role in the Higgs production and decay at the LHC. These vertices can be affected by various New Physics contributions, including new particles, anomalous Yukawa couplings, and so on. We point out

The large data sample of the ${B}_{c}$ meson collected at the LHC experiment and the HL-LHC experiment provides us the opportunity to study the ${B}_{c}$ decays and the related physics. In this paper, we investigate the effect of ${K}^{0}\ensuremath{

The decays ${K}^{*}(892)\ensuremath{\rightarrow}{K}_{S,L}^{0}\ensuremath{\pi}$ can be used to study $CP$ violation and $CPT$ violation. The ${K}^{*}(892)$ (hereinafter referred to as ${K}^{*}$) meson can be produced via $J/\ensuremath{\psi}$ decays a
