Abstract

Transverse momentum spectra of mesons produced in p+p collisions are studied in the framework of a thermalized cylinder model. In the region of high transverse momentum, the considered distributions have a tail part at the maximum energy of RHIC. A two-component distribution based upon the improved cylinder model is used to fit the experimental data of the PHENIX Collaboration. It is found that the improved approach can describe the meson production in the wider range of transverse momenta.
