To proceed with their dynamics, one needs to know all sorts of effective actions where various potentially interesting references are given in [8]. We would like to take advantage of Conformal Field Theory (CFT) and try to release more information about the structures of the BPS effective actions. Indeed one of our aims is to work out with CFT to get more **data** and increase our knowledge of deriving various string theory couplings and likewise various techniques to Effective Field Theory (EFT) couplings along the way can also be explored.
