We obtain a closed expression for the large-N effective coupling constant g = g(L,T,l). Different behavior depending on the magnitude of the fixed coupling constant l is found to lead to a ''critical'' value lc. If l < lc, only short-distance and/or high-temperature asymptotic freedom is found. For l > lc one also observes spatial confinement, which is destroyed by temperature effects. We find a confining length, Lc ~ 1.61 fm, that is close to the proton charge diameter ( » 1.74 fm) and a deconfining temperature, ~ 138 MeV, which is comparable to the estimated value of » 200 MeV for hadrons.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2012-10-10T20:37:59Z No. of bitstreams: 1 Khannaa, F.
