Extra States in c < 1 String Theory

  • Sunil Mukhi
Part of the NATO ASI Series book series (NSSB, volume 295)


A construction of elements of the BRS cohomology of ghost number ±1 in c < 1 string theory is described, and their two-point function computed on the sphere. The construction makes precise the relation between these extra states and null vectors. The physical states of ghost number +1 are found to be exact forms with respect to a “conjugate” BRS operator.
