Generalized structure of hadron-quark vertex function in Bethe-Salpeter framework: Applications to leptonic decays of V-mesons

Shashank Bhatnagar, Shi-Yuan Li

We employ the framework of Bethe-Salpeter equation under Covariant Instantaneous Ansatz (CIA) to study the leptonic decays of vector mesons. The structure of hadron-quark vertex fu…

The puzzles in and decays: possible implications for R-parity violating supersymmetry

Ya-Dong Yang, Rumin Wang, G. R. Lu

Recent experiments suggest that certain data of decays are inconsistent with the standard model expectations. We try to explain the discrepancies with R-parity violat…

A Neutral Two Flavor Loff Color Superconductor

Ioannis Giannakis, De-fu Hou, Hai-Cang Ren

In this paper we construct analytically a LOFF color superconducting state that is both color and charge neutral using the weak coupling approximation. We demonstrate that this sta…

Running coupling constant from lattice data and bulk viscosity of strange quark matter

Zheng Xiaoping, Kang Miao, Liu Xuewen +1

We study the bulk viscosity of strange quark matter (SQM) in a quasiparticle model at finite chemical potential by extrapolating the previous quasiparticle model of finite temperat…

Micro-canonical pentaquark production in $\ee$ annihilations

Fu-Ming Liu, Klaus Werner

The existence of pentaquarks, namely baryonic states made up of four quarks and one antiquark, became questionable, because the candidates, i.e. the peak, are seen in certain…

Parton Ladder Splitting and the Rapidity Dependence of Transverse Momentum Spectra in Deuteron-Gold Collisions at RHIC

Klaus Werner, Fu-Ming Liu, Tanguy Pierog

We present a phenomenological approach (EPOS), based on the parton model, but going much beyond, and try to understand proton-proton and deuteron-gold collisions, in particular the…

Charm Quark Energy Loss in QCD Matter

W. C. Xiang, H. T. Ding, D. C. Zhou +1

The energy loss of heavy quarks in a quark-gluon plasma of finite size is studied within the light-cone integral approach. A simple analytical formulation of the radiative energy l…
