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…
