Probing neutrino-night-quark effective scalar interactions from neutrino masses

Feng-Zhi Chen, Junlin Huang, Fanrong Xu

In this work, we use neutrino masses as a probe of the neutrino-light-quark effective scalar interactions. It is found that neutrinos can acquire masses not only from the usual lig…

Tensor-current contributions to B Anomalies

Qiaoyi Wen, Fanrong Xu

Tensor-current operators, potentially generated by scalar leptoquarks in grand unified theories (GUTs), are among the plausible new physics (NP) candidates suggested by the anomali…

B Anomalies in Two Higgs Doublet Model with Flavor Symmetry

Qiaoyi Wen, Fanrong Xu

The long-standing flavor anomalies in $b \to s ℓ^{+} ℓ^{-}$ and $b \to c ℓ I^½$ persist. In this work, we explore a specific flavor-gauged two-Higgs doublet model (FG2HDM) exte…

Correlating $B \to K^{(*)} I^½ I^ˉ ½$ and flavor anomalies in SMEFT

Feng-Zhi Chen, Qiaoyi Wen, Fanrong Xu

The recent measurement of $B (B^{+} \to K^{+} I^½ I^ˉ ½)$ by Belle-II reveals a $2.8 I ¨ $ deviation from the Standard Model (SM) prediction. Combining this with a prior Belle meas…
