Are the CKM anomalies induced by vector-like quarks? Limits from flavor changing and Standard Model precision tests
Benedetta Belfatto, Zurab Berezhiani
Recent high precision determinations of and indicate towards anomalies in the first row of the CKM matrix. Namely, determination of from superallowed bet…

The CKM unitarity problem: A trace of new physics at the TeV scale?
Benedetta Belfatto, Revaz Beradze, Zurab Berezhiani
After the recent high precision determinations of and , the first row of the CKM matrix shows more than deviation from unitarity. Two possible scenarios beyon…

How light the lepton flavor changing gauge bosons can be?
Zurab Berezhiani, Benedetta Belfatto
Spontaneous breaking of inter-family (horizontal) gauge symmetries can be at the origin of the mass hierarchy between the fermion families. The corresponding gauge bosons have flav…
