Abstract: (arXiv)

We present results on strange and multi-strange particle production in Au+Au collisions at

\sqrt{s_{NN}}=62.4

GeV as measured with the STAR detector at RHIC. Mid-rapidity transverse momentum spectra and integrated yields of

K^{0}_{S}

,

\Lambda

,

\Xi

,

\Omega

and their anti-particles are presented for different centrality classes. The particle yields and ratios follow a smooth energy dependence. Chemical freeze-out parameters, temperature, baryon chemical potential and strangeness saturation factor obtained from the particle yields are presented. Intermediate transverse momentum (

p_T

) phenomena are discussed based on the ratio of the measured baryon-to-meson spectra and nuclear modification factor. The centrality dependence of various measurements presented show a similar behavior as seen in Au+Au collisions at

\sqrt{s_{NN}}=200

GeV.
