A generalized approach to study low as well as high pT regime of transverse momentum spectra
Abstract
A good understanding of the transverse momentum (pT) spectra is pivotal in the study of QCD matter created during the heavy-ion collision. Considering the difference in the underlying particle production mechanism, pT spectra can be divided into two distinct regions. Low-pT region corresponds to particle produced in soft-processes whereas particles produced in hard processes dominate the high-pT regime of the spectra. We will discuss a unified formalism to explain both low as well as high-pT 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.
