Phys. Rev. Lett. 86, 4231–4234 (2001)Low-Energy Supersymmetry and the Tevatron Bottom-Quark Cross SectionReceived 1 December 2000; published in the issue dated 7 May 2001 A long-standing discrepancy between the bottom-quark production cross section and predictions of perturbative quantum chromodynamics is addressed. We show that pair production of light gluinos, of mass 12 to 16 GeV, with two-body decays into bottom quarks and light bottom squarks, yields a bottom-quark production rate in agreement with hadron collider data. We examine constraints on this scenario from low-energy data and make predictions that may be tested at the next run of the Fermilab Tevatron collider. © 2001 The American Physical Society URL:
