Bulk properties of charged particles as a function of pseudo-rapidity in pp collisions

We conduct a study on the kinetic freezeout conditions of charged particles produced in pp collisions at 0.9, 2.36, and 7 TeV in different pseudo-rapidity centers of bins. We extract the freezeout parameters by analyzing the CMS data with the help of the blast wave model with Boltzmann-Gibbs statistics. Our analysis reveals that the kinetic freezeout temperature, kinetic freezeout volume, and mean transverse momentum of the particles, exhibit a declining trend with increasing pseudo-rapidity. In contrast, the transverse flow velocity shows an opposite trend. It is also observed that the kinetic freezeout temperature, mean transverse momentum, and kinetic freezeout volume, increase with increasing the collision energy. Furthermore, we plot the correlations among the parameters. We report a positive correlation between the kinetic freezeout temperature and kinetic freezeout volume, and kinetic freezeout temperature and mean transverse momentum. In contrast, the correlation between the kinetic freezeout temperature and transverse flow velocity is negative. Our findings provide valuable insights into the dynamics of pp collisions and shed light on the properties of the produced particles under different energy and pseudo-rapidity conditions. This knowledge is crucial for further advancing our understanding of high-energy physics and the behavior of matter under extreme conditions.
