Supersymmetry Explanation for the Puzzling Bottom Quark Production Cross Section
Abstract
It has been known for a long time that the cross section for bottom-quark b production at hadron collider energies exceeds theoretical expectations. An additional contribution from pair-production of light gluinos g, of mass 12 to 16 GeV, with two-body decays into bottom quarks and light bottom squarks b, helps to obtain a b production rate in better agreement with data. The masses of the g and b are restricted further by the ratio of like-sign to opposite-sign leptons at hadron colliders. Constraints on this scenario from other data are examined, and predictions are made for various processes such as Upsilon decay into b's.
