N=2 SUPERSTRINGS WITH (1, 2M) SPACETIME SIGNATURE Academic Article

abstract

• We show that the N=2 superstring in d=2D6 real dimensions, with criticaly achieved by including background charges in the two real time directions, exhibits a "coordinate-freezing" phenomenon, whereby the momentum in one of the two time directions is constrained to take a specific value for each physical state. This effectively removes this time direction as a physical coordinate, leaving the theory with (1, d-2) real spacetime signature. Norm calculations for low-lying physical states suggest that the theory is ghost free. 1992.
