Relations 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...

Closed String Amplitudes in Open String Field Theory

We investigate gauge invariant operators corresponding to on-shell closed string states in open string field theory. Using both oscillator representation and conformal mapping techniques, we calculate a two closed string tachyon amplitude that connects two gauge invariant operators by an open string propagator. We find that this amplitude is in a complete agreement with the usual disc amplitude...

Tree and Loop Amplitudes in Open Twistor String Theory

We compute the one-loop gluon amplitude for the open twistor string model of Berkovits, using a symmetric form of the vertex operators. We discuss the classical solutions in various topologies and instanton sectors and the canonical quantization of the world sheet Lagrangian. We derive the N-point functions for the gluon tree and one-loop amplitudes, and calculate a general one-loop expression ...

Instanton amplitudes in open-closed topological string theory

I use the universal instanton formalism to discuss quantum effects in the openclosed topological string theory of a Calabi-Yau A-model, in the presence of a multiplywrapped ‘Floer’ D-brane. This gives a precise meaning (up to the issue of compactifying the relevant moduli spaces) to the instanton corrections which affect sigma model and topological string amplitudes. The cohomological formalism...

Conformal Supergravity Tree Amplitudes from Open Twistor String Theory

We display the vertex operators for all states in the conformal supergravity sector of the twistor string, as outlined by Berkovits and Witten. These include ‘dipole’ states, which are pairs of supergravitons that do not diagonalize the translation generators. We use canonical quantization of the open string version of Berkovits, and compute N -point tree level scattering amplitudes for gravito...
