The Single Flavor Color Superconductivity in a Magnetic Field

Bo Feng, Defu Hou, Hai-cang Ren +1

We investigate the single flavor color superconductivity in a magnetic field. Because of the absence of the electromagnetic Meissner effect, forming a nonspherical CSC phase, polar…

Jet Quenching with Parton evolution

Luan Cheng, Enke Wang

We report the evolution effects on jet energy loss with detailed balance. The initial conditions and parton evolution based on perturbative QCD in the chemical non-equilibrated med…

Gamma-Jet Tomography of Quark-Gluon Plasma in High-Energy Nuclear Collisions

Hanzhong Zhang, J. F. Owens, Enke Wang +1

Within the next-to-leading order (NLO) perturbative QCD (pQCD) parton model, suppression of away-side hadron spectra associated with a high photon due to parton energy loss…

Family Non-universal Z^\prime effects on \bar{B}_q-B_q$ mixing, B\to X_s μ^+μ^- and B_s\to μ^+μ^- Decays

Qin Chang, Xin-Qiang Li, Ya-Dong Yang

Motivated by the large discrepancy of CP-violating phase in mixing between the experimental data and the Standard Model prediction, we pursue possible solutions wit…

Elliptic flow of thermal photons at midrapidity in Au+Au collisions at GeV

Fu-Ming Liu, Tetsufumi Hirano, Klaus Werner +1

The elliptic flow of thermal photons at midrapidity in Au+Au collisions at GeV is predicted, based on three-dimensional ideal hydrodynamics. Because of…

The Subleading Term of the Strong Coupling Expansion of the Heavy-Quark Potential in a Super Yang-Mills Vacuum

Shao-xia Chu, Defu Hou, Hai-cang Ren

Applying the AdS/CFT correspondence, the expansion of the heavy-quark potential of the supersymmetric Yang-Mills theory at large is carried out to the sub-leadin…

Nonzero Mean Squared Momentum of Quarks in the Non-Perturbative QCD Vacuum

Li-Juan Zhou, Leonard S. Kisslinger, Wei-xing Ma

The non-local vacuum condensates of QCD describe the distributions of quarks and gluons in the non-perturbative QCD vacuum. Physically, this means that vacuum quarks and gluons hav…

A light-cone wavefunction approach to open heavy flavor dynamics in QCD matter

Rishi Sharma, Ivan Vitev, Ben-Wei Zhang

We calculate the lowest order charm and beauty parton distribution functions in and fragmentation functions into D and B mesons using the operator definitions of factorized perturb…

On Melting Temperature of Heavy Quarkonium with the AdS/CFT Implied Potential

Defu Hou, Hai-cang Ren

The quarkonium states in a quark-gluon plasma is examined with the potential implied by AdS/CFT duality. Both the vanila AdS-Schwarzschild metric and the one with an infrared cutof…

The imaginary part of the static gluon propagator in an anisotropic (viscous) QCD plasma

Adrian Dumitru, Yun Guo, Michael Strickland

We determine viscosity corrections to the retarded, advanced and symmetric gluon self energies and to the static propagator in the weak-coupling "hard loop" approximation to high-t…

QCD phase diagram and locating critical point using RHIC low energy scan data

Mingmei Xu, Meiling Yu, Lianshou Liu

It is shown that the RHIC energy-scan experiments can serve as an effective tool for studying the system evolution along the first order phase transition line passing the critical…

Critical phenomena in disc-percolation model and its application to relativistic heavy ion collisions

Hongwei Ke, Mingmei Xu, Lianshou Liu

Through studying the critical phenomena in continuum-percolation of discs, we find a new approach to locate the critical point, i.e. using the inflection point of as an…

Quarkonium states in an anisotropic QCD plasma

Adrian Dumitru, Yun Guo, Agnes Mocsy +1

We consider quarkonium in a hot QCD plasma which, due to expansion and non-zero viscosity, exhibits a local anisotropy in momentum space. At short distances the heavy-quark potenti…
