Renormalisation group analysis of scalar Leptoquark couplings addressing flavour anomalies: emergence of lepton-flavour universality

open access: yesJournal of High Energy Physics, 2023
Leptoquarks with masses between 2 TeV and 50 TeV are commonly invoked to explain deviations between data and Standard-Model (SM) predictions of several observables in the decays b → cτ ν ¯ $$ b\to c\tau \overline{\nu} $$ and b → sℓ + ℓ − with ℓ = e, μ ...

Revisiting Minimal Lepton Flavour Violation in the light of leptonic CP violation

open access: yesJournal of High Energy Physics, 2017
The Minimal Lepton Flavour Violation (MLFV) framework is discussed after the recent indication for CP violation in the leptonic sector. Among the three distinct versions of MLFV, the one with degenerate right-handed neutrinos will be disfavoured, if this

CP violation in Semi-Leptonic τ decays

open access: yesAIP Conference Proceedings, 2007
We study CP violation in semi-leptonic $τ$ decays and we determine the conditions necessary to be able to define a observable CP asymmetry. We apply these conditions in both models, the standard model for the electroweak interactions and its supersymmetric extensions.

Searching for new physics in the differential decay width of a Λb semi-leptonic decay

open access: yesModern Physics Letters A, 2022
We propose to investigate the effects of new physics in the semi-leptonic sequential decay [Formula: see text]. First, we write the general, model-independent, non-covariant expression of the differential decay width of the process. Then, we calculate that observable according to three different types of new physics interactions, which might explain ...

Search for top quark decays t → qH with H → γγ using the ATLAS detector [PDF]

open access: yes, 2014
A search is performed for flavour-changing neutral currents in the decay of a top quark to an up-type (c, u) quark and a Higgs boson, where the Higgs boson decays to two photons.

Semi-Leptonic D_s^+(1968) Decays as a Scalar Meson Probe [PDF]

open access: yes, 2011
The unusual multiplet structures associated with the light spin zero mesons have recently attracted a good deal of theoretical attention. Here we discuss some aspects associated with the possibility of getting new experimental information on this topic ...

B → K∗µ+µ− and Form Factors for Semi-Leptonic and Radiative B Decays [PDF]

open access: yes, 2010
The hadronic environment of the LHC favours the study of exclusive modes, and of these semi-leptonic and radiative B decays will play a leading role in the search for new physics (NP).

The kaon semileptonic form factor with near physical domain wall quarks [PDF]

open access: yes, 2013
We present a new calculation of the K → π semileptonic form factor at zero momentum transfer in domain wall lattice QCD with N f = 2+1 dynamical quark flavours. By using partially twisted boundary conditions we simulate directly at the phenomenologically

Uniting low-energy semileptonic and hadronic anomalies within SMEFT

open access: yesJournal of High Energy Physics
Two categories of four-fermion SMEFT operators are semileptonic (two quarks and two leptons) and hadronic (four quarks). At tree level, an operator of a given category contributes only to processes of the same category.
