1/N Expansion for a supersymmetric o(n) model in four dimensions

  • S. V. Ketov
Physics of Elementary Particles and Field Theory


An application is considered of the stationary phase method to computation of the generating functional of Green's functions [1, 2] for a four-dimensional supersymmetric σ-model [3, 4]. In the leading order in 1/V, a renormalized potential is obtained, which is unbound from below, unlike in a similar two-dimensional case [5].
