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 ...

Hydrodynamic effects on spin polarization along the beam direction in Au+Au and p+Pb collisions [PDF]
EPJ Web of ConferencesWe investigate hydrodynamic effects on the spin polarization of Λ hyperons in Au+Au collisions at √sNN = 200 GeV and p+Pb collisions at √sNN = 8.16 TeV using the CLVisc hydrodynamic framework.

Perturbations of bounce inflation scenario from f(T) modified gravity revisited
European Physical Journal C: Particles and Fields, 2019 In this work, we revisit the perturbations that are generated in the bounce inflation scenario constructed within the framework of f(T) theory. It has been well known that pure f(T) theory cannot give rise to bounce inflation behavior, so aside from the ...

LEPTON NUMBER AND LEPTON FLAVOR VIOLATIONS IN SEESAW MODELS [PDF]
Modern Physics Letters A, 2002 We discuss the impact of fermion mass matrices on some lepton number violating processes, namely baryogenesis via leptogenesis and neutrinoless double beta decay, and on some lepton flavor violating processes, namely radiative lepton decays in supersymmetric seesaw models.

Diffusion of charm quarks in jets in high-energy heavy-ion collisions
European Physical Journal C: Particles and Fields, 2019 The radial distribution of $$D^0$$ D0 mesons in jets probes the diffusion of charm quark relative to the jet axis and provides a new perspective to study the interaction mechanisms between heavy quarks and the medium in the nucleus-nucleus collisions ...

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.

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.

On sum rules for semi-leptonic b → c and b → u decays
Journal of High Energy PhysicsThe semi-leptonic b → clν processes are receiving a lot of attention, as the lepton flavor universality (LFU) violation has been hinted by the measured ratios R D ∗ $$ {R}_{D^{\left(\ast \right)}} $$ = Γ(B → D (∗) τν)/Γ(B → D (∗) ℓν) for ℓ = e, μ ...

Radiative Corrections to the Leptonic Decays of the Charged Heavy Leptons
, 1978 We present numerical estimates for the radiative corrections to the decays L∓ → e∓νeνL, μ∓ νμνL in the context of aV ±A interaction. The radiative corrections change the Michel parameter appreciably from its bareV ±A value, for the decay L∓ → e∓νeνL, and have a measurable effect on the electron energy spectrum.
