Lepton Numbers in the framework of Neutrino Mixing [PDF]

, 2001
In this short review we discuss the notion of lepton numbers. The strong evidence in favor of neutrino oscillations obtained recently in the Super-Kamiokande atmospheric neutrino experiment and in solar neutrino experiments imply that the law of ...

The global geometrical property of jet events in high-energy nuclear collisions

European Physical Journal C: Particles and Fields, 2020
We present the first theoretical study of medium modifications of the global geometrical pattern, i.e., transverse sphericity ( $$S_{\perp }$$ S ⊥ ) distribution of jet events with parton energy loss in relativistic heavy-ion collisions.

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 ...

$${b\rightarrow c\tau \nu }$$ b→cτν transitions in the standard model effective field theory

European Physical Journal C: Particles and Fields, 2019
The $$R(D^{(*)})$$ R(D(∗)) anomalies observed in $$B\rightarrow D^{(*)}\tau \nu $$ B→D(∗)τν decays have attracted much attention in recent years. In this paper, we study the $$B\rightarrow D^{(*)}\tau \nu $$ B→D(∗)τν , $$\Lambda _b\rightarrow \Lambda _c ...

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.

Charged-lepton mixing and lepton flavor violation

Physics Letters B, 2015
We present a model for calculating charged-lepton mixing matrices. These matrices are an essential ingredient for predicting lepton flavor-violating rates in the lepton number nonuniversal models recently proposed to explain anomalies in B-meson decays. The model is based on work on "constrained flavor breaking" by Appelquist, Bai and Piai relating the
