Laser-induced selection of longitudinal $Z$ bosons in resonant $e^{+} e^{-}$ annihilation

Fengye Chen, Qingzheng Lv, Libin Fu

Longitudinal $Z$-boson production is strongly suppressed in collinear $e^+e^-$ annihilation in vacuum due to current conservation and helicity selection. We show that this supp…

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…

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

Feng-Zhi Chen, Qiaoyi Wen, Fanrong Xu

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