DOI: 10.1103/physrevd.103.035004
Abstract: There is a newly emerging tension between determinations of ${V}_{us}$ from different sources (known as the Cabibbo anomaly), clearly demonstrated by the new $R({V}_{us})$ observable which is highly sensitive to lepton flavor universality violating effects.… read more here.

DOI: 10.1103/physrevd.99.033001
Abstract: We perform a comprehensive study of the Higgs couplings, gauge-boson couplings to fermions and triple gauge boson vertices. We work in the framework of effective theories including the effects of the dimension-six operators contributing to… read more here.

DOI: 10.1103/physrevlett.129.271801
Abstract: We assess the impact of the very recent measurement of the top-quark mass by the CMS Collaboration on the fit of electroweak data in the standard model and beyond, with particular emphasis on the prediction… read more here.
