in broken supersymmetry every fermion has a super partner that is a boson, with same internal quantum numbers, except mass. i.e superpartner of an electron is a selectron, which is a boson. in QFT gauge bosons are force carriers. gauge bosons with mass create a force that is short-ranged, wouldn't each and every fermion in the SM in SUSY create a gauge boson that is the susy-partner of a fermion, that also creates a new fundamental force of nature? all of these forces would be short-ranged. is there any experimental evidence of new, short-ranged fundamental forces predicted by SUSY associated with squarks selectrons stops, sneutrinos, etc?
