F. Antonuccio et S. Pinsky, ON THE TRANSITION FROM CONFINEMENT TO SCREENING IN QCD(1-N(1) COUPLEDTO ADJOINT FERMIONS AT FINITE), Physics letters. Section B, 439(1-2), 1998, pp. 142-149
We consider SU(N) QCD(1+1) coupled to massless adjoint Majorana fermio
ns, where N is finite but arbitrary. We examine the spectrum for vario
us values of N, paying particular attention to the formation of multi-
particle states, which were recently identified by Gross, Hashimoto an
d Klebanov in the N = infinity limit of the theory. it is believed tha
t in the limit of vanishing fermion mass, there is a transition from c
onfinement to screening in which string-like states made out of adjoin
t fermion bits dissociate into stable constituent ''single particles''
. In this work, we provide numerical evidence that such a transition i
nto stable constituent particles occurs not only at large N, but for a
ny finite value of N. In addition, we discuss certain issues concernin
g the ''topological'' properties exhibited by the DLCQ spectrum. (C) 1
