Strong-field control of the $Z$ -boson resonance in $e^{+} e^{-}$ collisions

Fengye Chen, Qingzheng Lv, Libin Fu

Resonant $Z$ -boson production is a cornerstone of precision electroweak physics, with its vacuum line shape set by the $Z$ mass, width, and collision kinematics. We show that a str…

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…
