$\pi ,K,p$ and $\bar{p}$ production from Au+Au collisions at $\sqrt{s_{{}_{NN}}}=62.4$ GeV

The preliminary results of ${\pi }^{\pm },K^{\pm },p$ and $\bar{p}$ spectra are reported from Au+Au collisions at $\sqrt{s_{{}_{NN}}}=62.4$ GeV. Particle identification is from the Time Projection Chamber and Time-of-Flight system at STAR. The nuclear modification factor $R_{CP}$ for mesons ($\pi^{\pm}, K^{\pm}$)andbaryons($p, \bar{p}$) will also be discussed.
