Phys. Rev. D 57, 6420–6428 (1998)Spectrum of a large N gauge theory near the transition from confinement to screeningReceived 17 November 1997; published in the issue dated 15 May 1998 We study the spectrum of (1+1)-dimensional large N QCD coupled to an adjoint Majorana fermion of mass m. As m⃗0 this model makes a transition from confinement to screening. We argue that in this limit the spectrum of single-string states develops a continuous part. The continuum begins at exactly twice the mass of the lightest bound state. This critical mass is nothing but the threshold for a decay into two lightest states. We present numerical results based on DLCQ that appear to support our claim. © 1998 The American Physical Society URL:
