Neutrino masses and lepton flavour violating phenomena in the MSSM [PDF]

open access: yes, 2007
The most general supersymmetric model with minimal particle content and an additional discrete Ƶ(_3) symmetry, which allows lepton number violating terms, is considered. In this model, we calculate at the level of one-loop the resulting Majorana neutrino

Extracting jet transport coefficient via single hadron and dihadron productions in high-energy heavy-ion collisions

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We study the suppressions of high transverse momentum single hadron and dihadron productions in high-energy heavy-ion collisions based on the framework of a next-to-leading-order perturbative QCD parton model combined with the higher-twist energy loss ...

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

open access: yesEuropean 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 ...

HFAG τ lepton averages and |Vus| determination with τ decays

open access: yes, 2015
We present an updated HFAG report for the τ lepton, using τ lepton experimental results available up to Summer 2014. World averages are computed for quantities where the HFAG procedures may produce improvements over the PDG compilation.

Chiral Phase Transition in Linear Sigma Model with Nonextensive Statistical Mechanics

open access: yesAdvances in High Energy Physics, 2017
From the nonextensive statistical mechanics, we investigate the chiral phase transition at finite temperature T and baryon chemical potential μB in the framework of the linear sigma model.

B s(d) − B ¯ $$ \overline{B} $$ s(d) mixing and B s → μ + μ − decay in the NMSSM with the Flavour Expansion Theorem

open access: yesJournal of High Energy Physics, 2019
In this paper, motivated by the observation that the Standard Model predictions are now above the experimental data for the mass difference ΔM s(d), we perform a detailed study of B s(d) − B ¯ $$ \overline{B} $$ s(d) mixing and B s → μ + μ − decay in the

Leptonic CP-violation and mirror leptons

open access: yesNuclear Physics B, 1986
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 ...

RD*,RK* $$ {R}_{D^{\left(*\right)}},{R}_{K^{\left(*\right)}} $$ and neutrino mass in the 2HDM-III with right-handed neutrinos

open access: yesJournal of High Energy Physics, 2018
Given that the two-Higgs-doublet model of type III (2HDM-III) has the potential to address the RD* $$ {R}_{D^{\left(*\right)}} $$ anomalies while the resolution to the RK* $$ {R}_{K^{\left(*\right)}} $$ deficits requires new degrees of freedom within ...

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

open access: yesEuropean 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.
