  Analysis of transverse momentum distributions is a useful tool to understand
the dynamics of relativistic particles produced in high energy collision.
Finding an accurate distribution function to approximate the spectra is a
vastly developing area of research in particle physics. In this work, we have
provided a detailed theoretical description of the application of the Pearson
statistical framework in high energy physics proposed for the first time in Ref
[6]. Here, the transverse momentum spectra of pions measured by experiments at
RHIC and LHC are also investigated in the framework of relativistic statistical
thermodynamics using Pearson distribution.
