Unambiguous fermionic-string amplitudes.
We show how to treat boundary divergences in heterotic string theory covariantly and unambiguously. The method applies even to theories with nonvanishing tadpoles; in this case the Fischler-Susskind mechanism sufficies to ensure well defined answers. Also n-point functions are well defined with no special string-tension renormalizations. As an example we find the loop corrections to the lineari...
متن کاملString Amplitudes from Moyal String Field Theory
We illustrate a basic framework for analytic computations of Feynman graphs using the Moyal star formulation of string field theory. We present efficient methods of computation based on (a) the monoid algebra in noncommutative space and (b) the conventional Feynman rules in Fourier space. The methods apply equally well to perturbative string states or nonperturbative string states involving D-b...
متن کاملTopological Amplitudes in String Theory
We show that certain type II string amplitudes at genus g are given by the topologi-cal partition function F g discussed recently by Bershadsky, Cecotti, Ooguri and Vafa. These amplitudes give rise to a term in the four-dimensional effective action of the form g F g W 2g , where W is the chiral superfield of N = 2 supergravitational multi-plet. The holomorphic anomaly of F g is related to non-l...
متن کاملRenormalization Group and String Amplitudes*
We define p-functions for open string tachyons away from the perturbative fixed point. We show that solutions of the renormalization group fixed point equations generate open string scattering amplitudes.

متن کاملRelations Between Closed String Amplitudes at Higher-order Tree Level and Open String Amplitudes
Abstract: KLT relations almost factorize closed string amplitudes on S2 by two open string tree amplitudes which correspond to the leftand the rightmoving sectors. In this paper, we investigate string amplitudes on D2 and RP2. We find that KLT factorization relations do not hold in these two cases. The relations between closed and open string amplitudes have new forms. On D2 and RP2, the leftan...
