摘要：
Pseudorapidity distributions of charged particles produced in p-(p) over bar or p-p collisions at different energies were reported by the UA5, UA1, P238, CDF, and ALICE collaborations. A multisource ideal gas model is used to fit the experimental data in this paper. According to the parameter values obtained from fitting the data, we find different linear relationships between different parameters and logarithmic center-of-mass energy. A prediction for the pseudorapidity distributions of charged particles produced in p-(p) over bar or p-p collisions at the higher Large Hadron Collider energies is given.
