High-precision muon decay predictions for ALP searches
P. Banerjee, A. M. Coutinho, T. Engel +3
We present an improved theoretical prediction of the positron energy spectrum for the polarised Michel decay . In addition to the full next-to-next-to-leadin…
Modified lepton couplings and the Cabibbo-angle anomaly
Antonio Coutinho, Andreas Crivellin, Claudio Andrea Manzari
Significant discrepancies between the different determinations of the Cabibbo angle have been observed. Here, we point out that this "Cabibbo-angle anomaly" can be explained by lep…
Global Fit to Modified Neutrino Couplings and the Cabibbo-Angle Anomaly
Antonio M. Coutinho, Andreas Crivellin, Claudio Andrea Manzari
Recently, discrepancies of up to between the different determinations of the Cabibbo angle were observed. This "Cabibbo-angle anomaly" could be explained by lepton flavour u…
: a Code for the Combination of Indirect and Direct Constraints on High Energy Physics Models
Jorge de Blas, Debtosh Chowdhury, Marco Ciuchini +15
is a flexible open-source tool which, given the Standard Model or any of its extensions, allows to fit the model parameters to a given set of experi…
New Physics in confronts new data on Lepton Universality
Marco Ciuchini, António M. Coutinho, Marco Fedele +4
In light of the very recent updates on the and measurements from the LHCb and Belle collaborations, we systematically explore here imprints of New Physics in $b \to…
Hadronic uncertainties in the decay
Marco Ciuchini, Antonio M. Coutinho, Marco Fedele +4
Motivated by the persisting 'anomaly' in the measurement of , we review hadronic uncertainties entering the angular observables of the decay $\bar B\to {\bar K}^*μ^+μ^-…
On Flavourful Easter eggs for New Physics hunger and Lepton Flavour Universality violation
Marco Ciuchini, Antonio M. Coutinho, Marco Fedele +4
Within the standard approach of effective field theory of weak interactions for transitions, we look for possibly unexpected subtle New Physics effects, here dubbed "flavo…
Natural Quasi-Alignment with two Higgs Doublets and RGE Stability
F. J. Botella, G. C. Branco, António M. Coutinho +2
In the context of two Higgs doublet models, we study the conditions required in order to have stable quasi-alignment in flavour space. We show that stability under the RGE imposes…
