Lepton Mixing Matrix Element U_{13} and New Assignments of Universal Texture for Quark and Lepton Mass Matrices [PDF]

Phys.Rev. D69 (2004) 117302, 2004
We reanalyze the mass matrix model of quarks and leptons that gives a unified description of quark and lepton mass matrices with the same texture form. By investigating possible types of assignment for the texture components of the lepton mass matrix, we find that a different assignment for neutrinos than for charged leptons can also lead to consistent

Search for medium response to jet quenching via hadron chemistry around the quenched jets [PDF]

EPJ Web of Conferences
We present a unique signal of medium response to jet quenching: the enhancement of baryon-to-meson ratios for associated particles at intermediate transverse momentum around the triggered quenched jets.

Leptons and photons [PDF]

Physics Letters B, 1996
It is assumed that three lepton families $( _e, e)$, $( _ , )$, $( _ , )$ carry charges, which are sources of electronic, muonic and tauonic massless vector particles, respectively. Various manifestations of these hypothetical photons are discussed.

Combined explanations of B-physics anomalies, $$(g-2)_{e, \mu }$$ ( g - 2 ) e , μ and neutrino masses by scalar leptoquarks

European Physical Journal C: Particles and Fields, 2022
We extend the contents of the standard model (SM) by introducing TeV-scale scalar leptoquarks to generate neutrino masses and explain some current observed deviations from the SM predictions, including the anomalous magnetic moments of charged leptons ...

Bounds On Anomalous Magnetic And Electric Moments Of Tau Lepton From LEP And Lepton Flavor Violation [PDF]

, 1999
The most stringent bounds on the anomalous magnetic and electric dipole moments of the tau lepton was derived by Escribano and Mass\'{o}[6] from the Z width at LEP in an effective lagrangian approach to the new physics.

YFS Resummation for Future Lepton-Lepton Colliders in SHERPA

SciPost Physics, 2022
We present an implementation of the Yennie-Frautschi-Suura (YFS) scheme for the all-orders resummation of logarithms from the emission of soft real and virtual photons in processes that are critical for future lepton colliders. They include, in particular, e^-e^+\to f\bar{f}e−e+→ff‾ and e^-e^+\to W^-W^+e−e+→W−W+, where we validate the results of our ...

Vector meson spectral function in a dynamical AdS/QCD model

European Physical Journal C: Particles and Fields, 2022
By using gauge/gravity duality, we calculate the spectral function of the heavy vector mesons with the presence of an intense magnetic field in a hot and dense medium.
