Optical leptons [PDF]

International Journal of Mathematics and Mathematical Sciences, 2004
We obtain optical vortices with classical orbital momentum ℓ = 1 and spin j = ±1/2 as exact solutions of a system of nonlinear Maxwell equations (NMEs). Two kinds of Kerr‐type media, namely, those with and without linear dispersion of the electric and the magnet susceptibility, are investigated. The electric and magnetic fields are represented as sums

Jet tomography in high-energy nuclear collisions [PDF]

EPJ 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 ...

Leptonic decays of the tau lepton [PDF]

EPJ Web of Conferences, 2019
In these proceedings we review the SM prediction for the tau leptonic decays, including the radiative $ (\tau \to \ell \lambda \nu \bar \nu ) $ and the five-body $ (\tau \to \ell \ell '\ell '\nu \bar \nu ) $ decay modes, which are among the most powerful tools to study precisely the structure of the weak interaction and to constrain possible ...

HFLAV $\tau$ branching fractions fit and measurements of Vus with $\tau$ lepton data [PDF]

, 2019
We report the status of the Heavy Flavour Averaging Group (HFLAV) averages of the $\tau$ lepton measurements We then update the latest published HFLAV global fit of the $\tau$ lepton branching fractions (Spring 2017) with recent results by BABAR.

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

Journal 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 ...

New leptons and old lepton numbers

Nuclear Physics B, 1976
Abstract We discuss, within the framework of SU(2) × U(1) gauge theories, possible relationships between the new leptons and the old ones. The importance of the radiative decays U− → e−γ and U− → μ−γ in experimentally determining these relationships is stressed.

3D structure of jet-induced diffusion wake [PDF]

EPJ Web of Conferences
Jet-induced diffusion wake in heavy-ion collisions has a unique 3D structure as manifested in the jet-hadron correlations in rapidity and azimuthal angle.

HFAG tau lepton averages

, 2014
The HFAG-Tau group has computed the world averages of the tau lepton properties using the experimental results available in early 2012. The tau lepton branching fractions, mass and lifetime are used to test lepton universality for charged weak currents ...
