Fermion Number

We investigate the R symmetries of standard-like superstring models. At the level of the cubic superpotential there are three global U(1) R symmetries. These are broken explicitly by N>3 terms in the superpotential and spontaneously by scalar vevs necessary to preserve supersymmetry at Mp. A Z2 discrete symmetry remains but is equivalent to fermion number modulo 2. These models possess an effective R-parity which arises from the interplay between the gauged U(1)B-L and U(1)r i+3.

Charge Formula

We consider orbifolds of two-dimensional unitary toroidal superconformal field theories with target spaces of arbitrary dimensions, where the orbifold group involves the space–time fermion number operator. We construct all so-called superaffine, orbifold prime and super-M-orbifold models by generalizing the constructions of Dixon, Ginsparg and Harvey. We also correct claims made by Dixon, Ginsparg and Harvey about multicritical points among those models with central charge [Formula: see text].
