I have a very basic question with respect to supersymmetry. Actually, I no clear idea at all what the effect of the superpartners (called gauginos??) of the exchange particles of interactions (photons, gravitons, gluon, W+-s and Z0s) on the corresponding interaction is. Example: Gravitation: According to supersymmetry apart from the graviton there is the gravitino. Does the gravitino contribute to the gravitational interaction ? As it is supposed to have high mass (compared to a proton for instance) its possible contribution should be only short-range. I would appreciate to learn more about this. Thank you
