On bulk singularity structures and all order α′ contact terms of BPS string amplitudes

The entire form of the amplitude of three SYM (involving two transverse scalar fields, a gauge field) and a potential Cn−1 Ramond–Ramond (RR) form field is found out. We first derive <VC−2VA0Vϕ0Vϕ0> and then start constructing an infinite number of t,s channel bulk singularity structures by me...
