We consider the production of gravitinos (\stackrel\ifmmode \else \~\fiG) in association with gluinos (\stackrel\ifmmode \else \~\fig) or squarks (\stackrel\ifmmode \else \~\fiq) at hadron colliders, including the three main subprocesses: qq\ensuremath→\stackrel\ifmmode \else \~\fig\stackrel\ifmmode \else \~\fiG, and q\stackrel\ensuremath→g\stackrel\ifmmode \else \~\fiq\stackrel\ifmmode \else \~\fiG, and g\stackrel\ensuremath→g\stackrel\ifmmode \else \~\fig\stackrel\ifmmode \else \~\fiG. These channels become enhanced to the point of being observable for sufficiently light gravitino masses (m_\stackrel\ifmmode \else \~\fiG<10^\ensuremath-4eV), as motivated by some supersymmetric explanations of the Collider Detector at Fermilab ee\ensuremathγ\ensuremathγ+ET,miss event. The characteristic signal of such events would be monojets, as opposed to dijets obtained in the more traditional supersymmetric process pp\ensuremath→\stackrel\ifmmode \else \~\fig\stackrel\ifmmode \else \~\fig. Searches for such events at the Fermilab Tevatron can impose lower limits on the gravitino mass. In the appendixes, we provide a complete set of Feynman rules for the gravitino interactions used in our calculation.
