More on closed string induced higher derivative interactions on D-branes

preprint2012arXivOpen access

Abstract

In our continued efforts of matching full string computations with the corresponding effective field theory computations, we evaluate string theory correlators in closed forms. In particular, we consider a correlator between three SYM vertex operators and one Ramond-Ramond CC-field vertex operator: <VCVϕVAVA><V_{C}V_ϕ V_AV_A>. We show that the infinite number of massless poles of this amplitude can be reproduced by the Born-Infeld action, the Wess-Zumino terms, and their higher derivative corrections. More specifically we find, up to an on-shell ambiguity, two scalar field and two gauge field couplings to all orders in α′α' such that the infinite number of massless poles of the field theory amplitude exactly match the infinite number of massless poles of S-matrix elements of <VCVϕVAVA><V_{C}V_ϕ V_AV_A>. We comment on close intertwinedness of an open string and a closed string that must be behind the matching.
