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 ...

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.

Hydrodynamic effects on spin polarization along the beam direction in Au+Au and p+Pb collisions [PDF]

EPJ Web of Conferences
We 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.

Studying energy–energy correlators in pp collisions at the LHC with a jet-free event-topology method

European Physical Journal C: Particles and Fields
We present a jet-free approach for measuring energy–energy correlators (EEC) in proton–proton (pp) collisions at the Large Hadron Collider (LHC), employing an event-topology method that does not rely on explicit jet reconstruction.
