Santosh K Das, Jan-e Alam, Payal Mohanty, Bikash Sinha

摘要:

研究了非零重子化学势对重夸克在富重子夸克-胶子等离子体中传播的阻力系数和扩散系数的影响。本文计算了低能碰撞中重味强子半轻子衰变产生的非光子单电子谱的核抑制因子$R_{\mathrm AA}$。非零重子化学势在$R_{\mathrm AA}$中的作用已被强调。

英文摘要:

The effects of non-zero baryonic chemical potential on the drag and diffusion coefficients of heavy quarks propagating through a baryon rich quark gluon plasma have been studied. The nuclear suppression factor, $R_{\mathrm AA}$ for non-photonic single electron spectra resulting from the semileptonic decays of hadrons containing heavy flavours have been evaluated for low energy collisions. The role of non-zero baryonic chemical potential on $R_{\mathrm AA}$ has been highlighted.
