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…
Correlating Non-Resonant Di-Electron Searches at the LHC to the Cabibbo-Angle Anomaly and Lepton Flavour Universality Violation
Andreas Crivellin, Claudio Andrea Manzari, Marc Montull
In addition to the existing strong indications for lepton flavour university violation (LFUV) in low energy precision experiments, CMS recently released an analysis of non-resonant…
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…
(Machine) Learning amplitudes for faster event generation
Fady Bishara, Marc Montull
We propose to replace the exact amplitudes used in MC event generators for trained Machine Learning regressors, with the aim of speeding up the evaluation of {\it slow} amplitudes.…
Diboson at the LHC vs LEP
Christophe Grojean, Marc Montull, Marc Riembau
We use the current CMS and ATLAS data for the leptonic channels to show that diboson production is, for a broad class of flavour models, already competitive with LE…
Light Higgs Boson from a Pole Attractor
Oleksii Matsedonskyi, Marc Montull
We propose a new way of explaining the observed Higgs mass, within the cosmological relaxation framework. The key feature distinguishing it from other scanning scenarios is that th…
Higgs Couplings in Composite Models
Marc Montull, Francesco Riva, Ennio Salvioni +1
We study Higgs couplings in the composite Higgs model based on the coset SO(5)/SO(4). We show that the couplings to gluons and photons are insensitive to the elementary-composite m…
SUSY Faces its Higgs Couplings
Rick S. Gupta, Marc Montull, Francesco Riva
In supersymmetric models, a correlation exists between the structure of the Higgs sector quartic potential and the coupling of the lightest CP-even Higgs to fermions and gauge boso…
Higgs discovery: the beginning or the end of natural EWSB?
Marc Montull, Francesco Riva
We use global fits to analyze the most recent Higgs data from ATLAS, CMS and Tevatron and compare the Standard Model (SM) prediction with natural extensions of the SM. In particula…
