    Abstract

    We study baryons in SU(N) gauge theories at finite temperature according to the gauge/string correspondence based on IIB string theory. The baryon is constructed out of the D5-brane and N fundamental strings to form a color singlet N-quark bound state. At finite temperature and in the deconfining phase, we could find k(<N)-quark baryons. Thermal properties of such k-quark baryons and also of the N-quark baryon are examined. We study the temperature dependence of color screening distance and the Debye length of the baryon of the k quark and the N quark. We also estimate the melting temperature, where the baryons decay into quarks and gluons completely.
