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