Becchi-Rouet-Stora-Tyutin properties of new superstring states

Dimitri Polyakov

Open full text 12 citations

Abstract

Branelike states are defined by physical vertex operators in Neveu-Schwarz-Ramond (NSR) superstring theory, existing at nonzero pictures only. These states exist both in open- and closed-string theories, in the NS and NS-NS sectors, respectively. In this paper, we present a detailed analysis of their Becchi-Rouet-Stora-Tyutin (BRST) properties, giving proof that these vertex operators are physical, i.e., BRST-invariant and BRST-nontrivial.
