Long strings and chiral primaries in the hybrid formalism

Long strings and chiral primaries in the hybrid formalism

Abstract We revisit two related phenomena in AdS3 string theory backgrounds. At pure NS-NS flux, the spectrum contains a continuum of long strings which can escape to the boundary of AdS3 at a finite cost of energy. Related to this are certain gaps in the BPS spectrum one computes from the RNS world...
