Covariant string field theory. II
Physical Review D, 1986The covariant string field theory is presented in its full detail for the closed-bosonic-string case. The properties of the interaction vertex of three closed strings are fully clarified. We thus establish the nilpotency of the full nonlinear Becchi-Rouet-Stora (BRS) transformation as well as the BRS invariance of our gauged-fixed action.

International Journal of Modern Physics A, 1987
String theory has emerged as the leading candidate for a unified field theory of all known forces. However, it is impossible to trust the various phenomenological predictions of superstring theory based on classical solutions alone. It appears that the crucial problem of the theory, breaking ten dimensional space-time down to four dimensions, must be ...

Physica Scripta, 1987
We review the construction of the free equations of motion for open and closed strings in 26 dimensions, using the methods of the Florida Group. Differing from previous treatments, we argue that the constraint L0 - 0 = 0 should not be imposed on all the fields of the closed string in the gauge invariant formalism; we show that it can be incorporated in

Conformal techniques in string theory and string field theory
Physics Reports, 1988Abstract The application of some conformal and Riemann surface techniques to string theory and string field theory is described. First a brief review of Riemann surface techniques and of the Polyakov approach to string theory is presented. This is followed by a discussion of some features of string field theory and of its Feynman rules. Specifically,

Closed strings in open-string field theory
Physical Review Letters, 1987An explicit construction of closed-string states is given in terms of open-string oscillators acting on the open-string Fock vacuum. The closed-open-open coupling is computed for the graviton and agrees with the standard result. The closed string states are not annihilated by the Becchi-Rouet-Stora-Tyutin operator Q.

Nonpolynomial String Field Theory [PDF]
, 1991 String field theory, so far, has been relatively clean and simple. For example, the light cone string field theory for closed strings [1] was purely cubic, yet it successfully reproduced the highly nonlinear theory of Einstein. The covariant version of the open string field theory [2] was even simpler, being just a Chern— Simons term.
