, Lepton Flavour Violation and Decays with Leptoquarks: Correlations and Future Prospects
Estefania Coluccio Leskow, Andreas Crivellin, Giancarlo D'Ambrosio +1
The long-standing anomaly in the anomalous magnetic moment of the muon indicates the presence of chirality violating new physics contributions. A possible solution involves scalar…
Complementarity in lepton-flavour violating muon decay experiments
A. Crivellin, S. Davidson, G. M. Pruna +1
This note presents an analysis of lepton-flavour-violating muon decays within the framework of a low-energy effective field theory that contains higher-dimensional operators allowe…
Probing lepton flavour (universality) violation at NA62 and future kaon experiments
Lewis C. Tunstall, Andreas Crivellin, Giancarlo D'Ambrosio +1
Recent results from the LHC's first run have revealed intriguing departures from lepton flavour universality in the semi-leptonic decays of -mesons. We discuss the complementary…
Lepton Flavor Non-Universality in B decays from Dynamical Yukawas
Andreas Crivellin, Javier Fuentes-Martin, Admir Greljo +1
The basic features of quark and lepton mass matrices can be successfully explained by natural minima of a generic potential with dynamical Yukawa fields invariant under the $[\math…
Loop effects of heavy new scalars and fermions in
Pere Arnan, Andreas Crivellin, Lars Hofer +1
Recent measurements of processes at LHCb and BELLE have revealed tensions at the level between the Standard Model (SM) prediction and the experimental resul…
Effective Field Theory with Two Higgs Doublets
Andreas Crivellin, Margherita Ghezzi, Massimiliano Procura
In this article we extend the effective field theory framework describing new physics effects to the case where the underlying low-energy theory is a Two-Higgs-Doublet model. We de…
