New Signatures of Squarks

Abstract

When the gluino is light and long lived, missing energy is a poor signature for both squarks and gluinos. Instead, $S_q{S}_q^{\ast }$ production in $e^{+}{e}^{-}$ and $p\bar{p}$ collisions characteristically results in events with $\ge 4$ jets. Methods are proposed for deciding whether an observed excess of 4-jet events is due to $S_q{S}_q^{\ast }$ production. The recent report by ALEPH of observation of 14 4-jet events when 7 were expected is discussed.

12/22/95 version (put on net 1/1/96) elaborates remarks on squarks as possible source of ALEPH 4-jet excess and adds a ref. latex, 10 pages (including 1 figure), uufiled
