Looking forward to lepton-flavor-violating ALPs [PDF]

open access: yesJournal of High Energy Physics, 2020
We assess the status of past and future experiments on lepton flavor violating (LFV) muon and tau decays into a light, invisible, axion-like particle (ALP), a.

Test of lepton flavor universality and search for lepton flavor violation in B → Kℓℓ decays

open access: yesJournal of High Energy Physics, 2021
We present measurements of the branching fractions for the decays B → Kμ+μ− and B → Ke+e−, and their ratio (RK), using a data sample of 711 fb−1 that contains 772 × 106BB¯\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{

Modular invariant quark and lepton models in double covering of S4 modular group [PDF]

open access: yesPhysical Review D, 2020
We perform a comprehensive analysis of the homogeneous finite modular group $\Gamma'_4\equiv S'_4$ which is the double covering of $S_4$ group. The weight 1 modular forms of level 4 are constructed in terms of Dedekind eta function, and they transform as

Lepton mixing and the charged-lepton mass ratios [PDF]

open access: yesJournal of High Energy Physics, 2018
Abstract We construct a class of renormalizable models for lepton mixing that generate predictions given in terms of the charged-lepton mass ratios. We show that one of those models leads, when one takes into account the known experimental values, to almost maximal CP -breaking phases and to almost maximal neutrinoless double-beta ...

Probing new physics in class-I B-meson decays into heavy-light final states

open access: yesJournal of High Energy Physics, 2021
With updated experimental data and improved theoretical calculations, several significant deviations are being observed between the Standard Model predictions and the experimental measurements of the branching ratios of B ¯ s 0 → D s ∗ + L ...

Neutrino Masses and Lepton Flavour Violation in Thick Brane Scenarios [PDF]

open access: yes, 2001
We address the issue of lepton flavour violation and neutrino masses in the ``fat-brane'' paradigm, where flavour changing processes are suppressed by localising different fermion field wave-functions at different positions (in the extra dimensions) in a

Jet tomography in high-energy nuclear collisions [PDF]

open access: yesEPJ Web of Conferences, 2019
When an energetic parton traversing the QCD medium, it may suffer multiple scatterings and lose energy. This jet quenching phenomenon may lead to the suppression of leading hadron productions as well as medium modifications of full jet observables in ...

Test of the universality of τ and μ lepton couplings in W-boson decays with the ATLAS detector [PDF]

open access: yesNature Physics, 2020
The standard model of particle physics encapsulates our best current understanding of physics at the smallest scales. A fundamental axiom of this theory is the universality of the couplings of the different generations of leptons to the electroweak gauge
