Covariant action for chiral boson strings
Kuzenko S. M. , Solov'ev O. A.
A covariant action is proposed for chiral boson strings with d space-time dimensions, with NL left-hand moving bosons, NR right-hand moving bosons, and 2NF nonpropagating Majorana-Weyl fermions. The theory is free of anomalies in the case iV* = NL = 26 </,NF = 2d.
