QCD Matter Thermalization at RHIC and LHC

Zhe Xu, Luan Cheng, Andrej El +2

Employing the perturbative QCD inspired parton cascade, we investigate kinetic and chemical equilibration of the partonic matter created in central heavy ion collisions at RHIC and…

Studying Double Charm Decays of B_{u,d} and B_{s} Mesons in the MSSM with R-parity Violation

C. S. Kim, Ru-Min Wang, Ya-Dong Yang

Motivated by the possible large direct CP asymmetry of \bar{B}^0_d \to D^+ D^- decay measured by Belle collaboration, we investigate double charm B_{u,d} and B_s decays in the mini…

Higher Angular Momentum Mixing in a Non-spherical Color Superconductor with Time Reversal Invariance Violation

Bo Feng, Defu Hou, Hai-cang Ren

The angular momentum mixing in a non-spherical CSC with nonzero azimuthal quantum number and therefore violating time reversal invariance has been examined. The mixing is bound to…

Viscous Effects on Elliptic Flow and Shock Waves

I. Bouras, L. Cheng, A. El +4

Fast thermalization and a strong buildup of elliptic flow of QCD matter as found at RHIC are understood as the consequence of perturbative QCD (pQCD) interactions within the 3+1 di…

Jet quenching and direct photon production

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

Jet quenching effect has been investigated in the direct photon production, based on a realistic data-constrained (3+1) dimensional hydrodynamic description of the expanding hot an…

Angular Momentum Mixing in Single Flavor Color Superconductivity with Transverse Pairing

Bo Feng, Defu Hou, Hai-cang Ren

Because of the equal strength of the pairing potential mediated by one-gluon exchange for all partial waves to the leading order QCD running coupling constant and the nonlinearity…

The theory and phenomenology of jets in nuclear collisions

Ivan Vitev, Ben-Wei Zhang, Simon Wicks

We review selected results from a recent in-depth study of jet shapes and jet cross sections in ultra-relativistic reactions with heavy nuclei at the LHC arXiv:0810.2807 [hep-ph].…

A theory of jet shapes and cross sections: from hadrons to nuclei

Ivan Vitev, Simon Wicks, Ben-Wei Zhang

For jets, with great power comes great opportunity. The unprecedented center of mass energies available at the LHC open new windows on the QGP: we demonstrate that jet shape and je…
