A low-energy supersymmetry scenario with a light gluino of mass 12 - 16 GeVand light sbottom (b1) of mass 2 - 6 GeV has been used to explain the apparentoverproduction of b quarks at the Tevatron. In this scenario the other masseigenstate of the sbottom, i.e. b2, is favored to be lighter than 180 GeV dueto constraints from electroweak precision data. We survey its decay modes inthis scenario and show that decay into a b quark and gluino should be dominant.Associated sbottom production at LEP via e+ e- -> Z* -> b1 b2* + b1* b2 isstudied and we show that it is naturally a three-jet process with a smallcross-section, increasingly obscured by a large Standard Model background forheavier b2. However we find that direct observation of a b2 at the 5-sigmalevel is possible if it is lighter than 110 - 129 GeV, depending on the sbottommixing angle |cos(theta_b)| = 0.30 - 0.45. We also show that b2-pair productioncan be mistaken for production of neutral MSSM Higgs bosons in the channel e+e- -> h^0 A^0 -> b b-bar b b-bar. Using searches for the latter we place alower mass limit of 90 GeV on b2.Comment: Error in significance calculation correcte

Can there be a heavy sbottom hidden in three-jet data at CERN LEP?
