论文摘要
对横向动量$（p_t）$光谱的良好理解在重型离子碰撞期间创建的QCD物质方面至关重要。考虑到潜在粒子生产机制的差异，$ p_t $ speptra可以分为两个不同的区域。低$ p_t $区域对应于软过程中产生的粒子，而在硬过程中产生的粒子主导了光谱的高$ p_t $制度。我们将讨论一种统一的形式主义，以一致的方式解释横向动量光谱的低和$ P_T $区域。这种统一的形式主义基于使用皮尔森分布对非扩展统计力学的概括。这种普遍的形式主义还深入了解了重型离子碰撞中椭圆流的研究。
A good understanding of the transverse momentum $(p_T)$ spectra is pivotal in the study of QCD matter created during the heavy-ion collision. Considering the difference in the underlying particle production mechanism, $p_T$ spectra can be divided into two distinct regions. Low-$p_T$ region corresponds to particle produced in soft-processes whereas particles produced in hard processes dominate the high-$p_T$ regime of the spectra. We will discuss a unified formalism to explain both low as well as high-$p_T$ region of the transverse momentum spectra in a consistent manner. This unified formalism is based on the generalisation of non-extensive statistical mechanics using the Pearson distribution. This generalised formalism also gives a strong insight into the study of elliptic flow in heavy-ion collision.
