Abstract
Null strings are the analog of massless particles, namely strings with zero tension or infinite slope. We present the supersymmetric extension of the null bosonic string constraint algebra and, in order to quantize covariantly, construct the corresponding BRST charge. We find that the null supersymmetric (bosonic) string is quantum consistent only in D = 10 (D = 26). The anomalies are generated only in the single Virasoro subalgebra associated to the tangenial direction.
