On SYM theory and all order bulk singularity structures of BPS strings in type II theory

摘要

The complete forms of the S-matrix elements of a transverse scalar field, two world volume gauge fields, and a Potential Cn-1 Ramond-Ramond (RR) form field are investigated. In order to find an infinite number of t, s, (t + s + u)-channel bulk singularity structures of this particular mixed open-closed amplitude, we employ all the conformal field theory techniques to VC-2V phi 0VA0VA0 , exploring all the entire correlation functions and all order alpha' contact interactions to these supersymmetric Yang-Mills (SYM) couplings. Singularity and contact term comparisons with the other symmetric analysis, VC-1V phi 0VA-1VA0 and VC-1V phi-1VA0VA0 are also carried out in detail. Various couplings from pull-Back of branes, Myers terms and several generalized Bianchi identities should be taken into account to be able to reconstruct all order alpha' bulk singularities of type IIB (IIA) superstring theory. Finally, we make a comment on how to derive without any ambiguity all order alpha'contact terms of this S-matrix which carry momentum of RR in transverse directions. (C) 2018 The Author.
