Green-Schwarz Action and Loop Calculations for Superstring.

摘要

The authors state that Green-Schwartz explicitly 10d supersymmetric and 2d covariant approach without spin 1/2 and 3/2 fields on world sheet may appear suitable for calculations of loops in superstring theory. The cancellation of Polyakov anomaly is realized and the answer for 1-loop 4-point amplitudes are reproduced. 18 refs. (Atomindex citation 19:096311)
