Short Distance Corrections to Scattering Processes

It is expected from T-duality in string theory that the background geometry of spacetime will be deformed due to the existence of an intrinsic extended structure. This short distance correction to the structure of spacetime can have low energy consequences, if such a deformation occurs at a scale much larger than Planck scale. So, we will analyze the effect of such a short distance correction on scattering processes. We explicitly calculate corrections to the Green function of Lippman-Schwinger equation and to the conserved current, and then use them to analyze short distance corrections to a scattering processes, and to obtain the corrected differential flux for the system under consideration. It may be noted that similar corrections will occur for all scattering process, as these corrections are induced by an intrinsic extended structure in spacetime.
