Global Analysis of Leptophilic Z' Bosons
Andrzej J. Buras, Andreas Crivellin, Fiona Kirk +2
New neutral heavy gauge bosons () are predicted within many extensions of the Standard Model. While in case they couple to quarks the LHC bounds are very stringent, lepto…
Precision from the diphoton Zh channel at FCC-hh
Fady Bishara, Stefania De Curtis, Luigi Delle Rose +5
The future 100 TeV FCC-hh hadron collider will give access to rare but clean final states which are out of reach of the HL-LHC. One such process is the production channel in t…
Global Electroweak Fit and Vector-Like Leptons in Light of the Cabibbo Angle Anomaly
Andreas Crivellin, Fiona Kirk, Claudio Andrea Manzari +1
The "Cabibbo Angle Anomaly" (CAA) originates from the disagreement between the CKM elements and extracted from superallowed beta and kaon decays, respectively, on…
Explaining and the Cabibbo Angle Anomaly with a Vector Triplet
Bernat Capdevila, Andreas Crivellin, Claudio Andrea Manzari +1
The most statistically significant hints for new physics in the flavor sector are discrepancies between theory and experiment in decays to lepton pairs () a…
A New Precision Process at FCC-hh: the diphoton leptonic Wh channel
Fady Bishara, Philipp Englert, Christophe Grojean +3
The increase in luminosity and center of mass energy at the FCC-hh will open up new clean channels where BSM contributions are enhanced at high energy. In this paper we study one s…
Hadronic vacuum polarization: versus global electroweak fits
Andreas Crivellin, Martin Hoferichter, Claudio Andrea Manzari +1
Hadronic vacuum polarization (HVP) is not only a critical part of the Standard Model (SM) prediction for the anomalous magnetic moment of the muon , but also a crucial ing…
