Detecting supersymmetric hadrons

Supersymmetric grand unified models are of interest because they offer a possible explanation of the great disparity between the W mass and the grand unified scale (about 1015 GeV). In such models each of the familiar particles (gluons, quarks, etc.) has a partner differing by 1/2 unit of spin, presumably with a mass of order the W mass or less. Supersymmetry ensures that the couplings of the partners of the gluons and quarks to normal hadronic constituents are of about the usual QCD strength. Thus production cross-sections for these states need not be particularly small. In the present paper we investigate the possibility of detecting the sypersymmetric partners of gluons and quarks at a 400 x 400 GeV/c proton-proton collider
