摘要:

在本文中,我们在介质修正的夸克-反夸克势框架下,采用非相对论量子色动力学方法和Born近似,研究了粲偶素和底偶素基态的微分散射截面。为此,我们采用了依赖于重子化学势($μ$b)和温度的准粒子(QP)Debye质量,从而研究了在固定散射角($θ=90^\circ$)下微分散射截面随重子化学势和温度的变化。我们还研究了在固定温度和重子化学势下微分散射截面随散射角$θ$(以度为单位)的变化。此外,我们还研究了在$θ=90^\circ$时碰撞参数和横动量对微分散射截面的影响。

英文摘要:

In the present work we have studied the Differential Scattering Cross-section for ground states of charmonium and bottomonium in the frame work of the medium modified form of quark-antiquark potential and Born-approximation using the non-relativistic quantum chromo-dynamics approach. To reach this end, quasi-particle (QP) Debye mass depending upon baryonic chemical potential ($μ$b) and temperature has been employed and hence the variation of Differential Scattering Cross-section with baryonic chemical potential and temperature at fixed value of the scattering angle ($θ=90^\circ$) has been studied. The variation of Differential Scattering Cross-section with scattering angle $θ$ (in degree) at fixed temperature and baryonic chemical potential has also been studied. We have also studied the effect of impact parameter and transverse momentum on differential scattering cross-section at $θ=90^\circ$.
