Baryon mass and phase transitions in large N gauge theory

Abstract

We calculate the baryon mass in N = 4 large N gauge theory by means of AdS/CFT correspondence and show that it is a truly bound state, at least in some situations. We find that a phase transition occurs at a critical temperature. Furthermore, we find there are bound states of W-bosons in the Higgs phase, where the gauge group is broken to SU(N1) × SU(N2).
