The exact mass-gap of the supersymmetric O(N) sigma model
A formula for the mass-gap of the supersymmetric O(N) sigma model (N>4) in two dimensions is derived: m/\Lambda_{\overline{\rm MS}}=2^{2\Delta}\sin(\pi\Delta)/(\pi\Delta), where \Delta=1/(N-2) and m is the mass of the fundamental vector particle in the theory. This result is obtained by comparing...
