Charged Pion Spectra in Au+Au Collisions at \srt=62.4 GeV

The combination of the ionization energy loss (dE/dx) from Time Projection Chamber (TPC) at $\simeq 8$% resolution and multi-gap resistive plate chamber time-of-flight (TOF) at 85$ps$ provides powerful particle identification. We present spectra of identified charged pions from transverse momentum $p_T\simeq 0.2$ GeV/c to ~7-8 GeV/c in Au+Au collisions at $\sqrt{s_{{}_{NN}}}=62.4$ GeV. Physics implications will be discussed.
