Title: Experimental signatures of low energy gauge-mediated supersymmetry breaking

Abstract

The experimental signatures for low energy gauge-mediated supersymmetry breaking are distinctive since the gravitino is naturally the lightest supersymmetric particle. The next lightest supersymmetric particle (NLSP) can be a gaugino, Higgsino, or right handed slepton. For a significant range of parameters, decay of the NLSP to its partner plus the gravitino can be measured as a displaced vertex or kink in a charged particle track. In the case that the NLSP is mostly gaugino, we identify the discovery modes as {ital e}{sup +}{ital e}{sup {minus}}{r_arrow}{gamma}{gamma}+{ital E}/, and {bar {ital pp}}{r_arrow}{ital l}{sup +}{ital l}{sup {minus}}{gamma}{gamma}+{ital E}/{sub {ital T}}. If the NLSP is a right-handed slepton, the discovery modes are {ital e}{sup +}{ital e}{sup {minus}}{r_arrow}{ital l}{sup +}{ital l}{sup {minus}}+{ital E}/ and {bar {ital pp}}{r_arrow}{ital l}{sup +}{ital l}{sup {minus}}+{ital E}/{sub {ital T}}. A NLSP which is mostly Higgsino is also considered. {copyright} {ital 1996 American Institute of Physics.}
