Charged lepton flavor violation on target at GeV scale
, 2015 We study the lepton flavor violating process, $e+ T \to \tau +T'$, at a few GeV. This process can be studied by experiments directing GeV scale electron or positron beams on internal or fixed targets. We study the effects of some low energy lepton flavor

Test of lepton flavour violation at LHC
, 2006 We study lepton flavour violating decays of neutralinos and sleptons within the Minimal Supersymmetric Standard Model, assuming two and three generation mixings in the slepton sector.

Multi-Lepton and Isolated Lepton Events at HERA
, 2009 Measurements of the production of events containing isolated high energy leptons (electrons and muons) produced in ep collisions have been performed with the H1 and ZEUS detectors at HERA, using data collected in the period 1994-2007. Topologies with more than one charged lepton or with a charged lepton in coincidence with missing transverse momentum ...

Nuclear suppression of the $$\phi $$ ϕ meson yields with large $$p_T$$ p T at the RHIC and the LHC
European Physical Journal C: Particles and Fields, 2017 We calculate $$\phi $$ ϕ meson transverse momentum spectra in $$\mathrm{p}+\mathrm{p}$$ p + p collisions as well as their nuclear suppressions in central $$\mathrm{A}+\mathrm{A}$$ A + A collisions both at the RHIC and the LHC in LO and NLO with the QCD ...

Lepton asymmetry and the cosmic QCD transition
, 2009 We study the influence of lepton asymmetry on the evolution of the early Universe. The lepton asymmetry $l$ is poorly constrained by observations and might be orders of magnitude larger than the baryon asymmetry $b$, $|l|/b \leq 2\times 10^8$.

Leptonic CP violation and Wolfenstein parametrization for lepton mixing
Physics Letters B, 2014 We investigate a general structure of lepton mixing matrix resulting from the SU$_F$(3) gauge family model with an appropriate vacuum structure of SU$_F$(3) symmetry breaking. It is shown that the lepton mixing matrix can be parametrized by using the Wolfenstein parametrization method to characterize its deviation from the tri-bimaximal mixing.

European Physical Journal C: Particles and Fields, 2019 In this work, we pave the way to calculate the productions of $$\omega $$ ω and $$K^0_{\mathrm{S}}$$ KS0 mesons with large $$p_T$$ pT in p+p and A+A collisions both at RHIC and LHC.

K0-K¯0 Mixing in the Minimal Flavor-Violating Two-Higgs-Doublet Models
Advances in High Energy Physics, 2017 The two-Higgs-doublet model (2HDM), as one of the simplest extensions of the Standard Model (SM), is obtained by adding another scalar doublet to the SM and is featured by a pair of charged Higgs, which could affect many low-energy processes.

Study of isolated-photon and jet momentum imbalance in pp and PbPb collisions
Nuclear Physics B, 2018 In this paper, we study the production of isolated-photon plus a jet in pp and PbPb collisions, which can be used as an important probe to the jet transport property in quark gluon plasma created in heavy ion collisions.

, 2004 We discuss the interaction of photons with neutrinos including two lepton loops. The parity violation in the gamma-nu to gamma-nu channel due to two lepton loops is substantially enhanced relative to the one lepton loop contribution.
