Description

It is important to study the particle production as a function of both transverse momentum ($p_{T}$) and particle species which provide crucial input for modeling of hadronic interactions and the hadronization process in high-energy collisions [1]. In this contribution, we will present the results on $\pi^{\pm}$, $K^{\pm}$, $p$ and $\bar{p}$ in $p+p$ collisions at $\sqrt{s}$ = 62.4 GeV from STAR experiment at the Relativistic Heavy Ion Collider. The results are obtained for the midrapidity region in the range $\mid{y}\mid < 0.1$. Charged hadrons are identified by using specific ionization energy loss at the low momentum region (about 1 GeV/$c$) with STAR's Time Projection Chamber detector [2,3]. We will present the final corrected $p_{T}$ spectra, particle yields (dN/dy), various particle ratios and mean $p_{T}$. The results will be compared with different models namely PYTHIA and PHOJET. **References** 1. H. Satz, Rep. Prog. Phys. 63, 151 (2000). 2. H. Bichsel, Nucl. Instrum. Meth. A 562, 154-197 (2006). 3.
