Abstract

We compute correlation functions in $N = 2$ non critical superstrings on the sphere. Our calculations are restrained to the ( $s = 0$ ) bulk amplitudes. We show that the four point function factorizes as a consequence of the non-critical kinematics, but differently from the $N = 0, 1$ cases no extra discrete state appears in the $c^\to 1^{-}$ limit.
