Modular invariant models of lepton masses at levels 4 and 5 [PDF]
We explore alternative descriptions of the charged lepton sector in modular invariant models of lepton masses and mixing angles. In addition to the modulus, the symmetry breaking sector of our models includes ordinary flavons.

Parametrized leptogenesis from linear seesaw
We present a purely linear seesaw mechanism in a mirror left-right symmetric framework and then realize a novel leptogenesis scenario for parametrizing the cosmic baryon asymmetry by the charged lepton masses, the light Majorana neutrino mass matrix and ...

The main highlights discussed at TAU2012 are briefly summarized. Besides the standard topics on lepton physics covered also at previous conferences (universality, QCD tests, V_{us} determination from tau decay, g-2, neutrino oscillations, lepton-flavour ...

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

Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Experimental Review on Lepton Universality and Lepton Flavour Violation tests in B decays [PDF]
Tests of lepton flavour universality in B decays offer an excellent opportunity to test the Standard Model, and show hints of new physics in analyses performed by the LHCb, Belle and BaBar experiments.

Leptonic CP-violation and mirror leptons
We study leptonic CP-violation within a single fermion generation in an extended electro-weak model where new right-handed leptons, so-called mirror leptons, exist and mix with standard left-handed leptons. Essential differences are pointed out between the mixing of a left-handed neutrino with a mirror neutrino in such a model and the ordinary mixing ...

YFS Resummation for Future Lepton-Lepton Colliders in SHERPA
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 ...

Neutrinoloser Doppelbetazerfall: Der Gral der Neutrinophysik
Die Entschlüsselung der Neutrinoeigenschaften ist auch siebzig Jahre nach ihrer Entdeckung noch nicht abgeschlossen. Es wäre eine spektakuläre Entdeckung, sollten Neutrinos ihre eigenen Antiteilchen sein und sich folglich als Majorana‐Teilchen entpuppen. Mehrere Experimente untersuchen diese Möglichkeit.
