B. Mukhopadhyaya et S. Roy, FILTERING OUT SIGNALS OF GAUGE-MEDIATED SUPERSYMMETRY BREAKING - CAN WE ALWAYS ELIMINATE CONVENTIONAL SUPERSYMMETRIC EFFECTS, Physical review. D. Particles and fields, 57(11), 1998, pp. 6793-6798
We investigate the signal gamma gamma+E in a high-energy linear e(+)e(
-) collider, with a view to differentiating between gauge-mediated sup
ersymmetry breaking and the conventional supersymmetric models. Prima
facie, there is considerable chance of confusion between the two scena
rios if the assumption of gaugino mass unification is relaxed. We show
that the use of polarized electron beams enables one to distinguish b
etween the two schemes in most cases. There are some regions in the pa
rameter space where this idea does not work, and we suggest some addit
ional methods of distinction. We also perform an analysis of some sign
als in the gauge-mediated model, coming from the pair production of th
e second-lightest neutralino.
