Multiple Parton Scattering in Nuclei: Heavy Quark Energy Loss and Modified Fragmentation Functions
, 2004 Multiple scattering, induced radiative energy loss and modified fragmentation functions of a heavy quark in nuclear matter are studied within the framework of generalized factorization in perturbative QCD. Modified heavy quark fragmentation functions and

European 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 ...

Vector meson spectral function in a dynamical AdS/QCD model
European Physical Journal C: Particles and Fields, 2022 By using gauge/gravity duality, we calculate the spectral function of the heavy vector mesons with the presence of an intense magnetic field in a hot and dense medium.

Mesons states and their dependence on spin and isospin
Iranian Journal of Physics Research, 2008 Meson is composed of one quark and one antiquark moving under the effect of confinement, oscillating and color potentials. Since quarks are particles with spin , there is a spin-spin interaction potential.

Potential analysis of holographic Schwinger effect in the magnetized background
European Physical Journal C: Particles and Fields, 2020 We study the holographic Schwinger effect with magnetic field at RHIC and LHC energies by using the AdS/CFT correspondence. We consider both weak and strong magnetic field cases with $$B\ll T^2$$ B≪T2 and $$B\gg T^2$$ B≫T2 solutions respectively. Firstly,

The decomposition of neutron-antineutron oscillation operators
Journal of High Energy Physics, 2023 We study the systematic decomposition of the dimension nine neutron-antineutron oscillation operators at tree and one-loop levels. We discuss the topologies’ generation and the assignment of the chiral quarks.

Harmonic quarks: properties and some applications [PDF]
arXiv, 2003 In this work the investigation of hadronic structures with the help of the harmonic quarks is prolonged. The harmonic quark model is good at describing the meson structures and the baryon excitations to resonances, in particular delta(1232). Harmonic quark reactions form the structure of the baryon resonances.

A New Property of the Quark-Antiquark Potential in a Quark-Gluon Plasma [PDF]
arXiv, 2000 I consider the behavior of the quark-antiquark potential, called the Cornell Potential, in a quark-gluon plasma. Since mesons are no longer bound in the quark-gluon plasma, there might be a relationship between the string tension of the quark-antiquark potential, the mass of the quark, and the coupling constant.

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.
