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 (up to 1.10 GeV/c) with STAR's Time Projection Chamber detector [2,3]. We will present the final corrected $p_{T}$ spectra, particle yields and various particle ratios. The results will be compared with different models namely PYTHIA and PHOJET. References: [1] H.
