Berkovits, Nathan [UNESP]2014-05-272014-05-271999-02-15Physical Review D - Particles, Fields, Gravitation and Cosmology, v. 59, n. 4, p. 1-, 1999.0556-2821http://hdl.handle.net/11449/130701Deriglazov and Galajinsky have recently proposed a new covariant action for the Green-Schwarz superstring which can be constructed in any spacetime dimension. In this Comment, I show that their action contains extra on-shell degrees of freedom as compared with the standard action and is therefore inequivalent. ©1999 The American Physical Society.1engArtigo10.1103/PhysRevD.59.048901WOS:000079938100092Acesso aberto2-s2.0-166443852842-s2.0-16644385284.pdf
