Conversion-Driven Baryogenesis in Flavored Dark Matter Models
Benedetta Belfatto, Monika Blanke, Jan Heisig +2
The dark matter and baryon asymmetry problems remain two of the most pressing questions in fundamental physics. Considering lepton-flavored dark matter, it has recently been shown…
Toward a Comprehensive Exploration of Flavored Dark Matter Models
Benedetta Belfatto, Monika Blanke, Jan Heisig +3
We present a comprehensive framework for the study of flavored dark matter models, combining relic density calculations with direct and indirect detection limits, collider constrai…
Vector-like quark doublets, weak-basis invariants and CP violation
F. Albergaria, J. F. Bastos, B. Belfatto +4
We study Standard Model extensions with isodoublet vector-like quarks with standard charges. Their presence induces right-handed charged and neutral currents. We identify minimal s…
Towards understanding fermion masses and mixings
Zurab Berezhiani, Benedetta Belfatto
The Standard Model does not constrain the form of the Yukawa matrices and thus the origin of fermion mass hierarchies and mixing pattern remains puzzling. On the other hand, there…
Minimally modified Fritzsch texture for quark masses and CKM mixing
Benedetta Belfatto, Zurab Berezhiani
The Standard Model does not constrain the form of the Yukawa matrices and thus the origin of fermion mass hierarchies and mixing pattern remains puzzling. On the other hand, there…
The remarkable role of the vector-like quark doublet in the Cabibbo angle and -mass anomalies
Benedetta Belfatto, Sokratis Trifinopoulos
The combination of precise determinations of and hints towards a violation of the CKM first row unitarity at about level. Conversely, the recent measurement…
Dark Matter abundance via thermal decays and leptoquark mediators
Benedetta Belfatto, Dario Buttazzo, Christian Gross +5
We explore a new mechanism for reproducing the Dark Matter (DM) abundance: scatterings of one DM particle on light Standard Model particles. Strong bounds on its decays can be sati…
Unveiling Hidden Physics at the LHC
Oliver Fischer, Bruce Mellado, Stefan Antusch +30
The field of particle physics is at the crossroads. The discovery of a Higgs-like boson completed the Standard Model (SM), but the lacking observation of convincing resonances Beyo…
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…
