Search for squarks and gluinos in events containing jets and a large imbalance in transverse energy

Using data corresponding to an integrated luminosity of 79 pb(-1), D0 has searched for events containing multiple jets and large missing transverse energy in p (p) over bar collisions at root s = 1.8 TeV at the Fermilab Tevatron collider. Observing no significant excess beyond what is expected from the standard model, we set limits on the masses of squarks and gluinos and on the model parameters m(0) and m(1/2), in the framework of the minimal low-energy supergravity models of supersymmetry. For tan beta = 2 and A(0) = 0, with mu < 0, we exclude all models with m(q) < 250 GeV/c(2). For models with equal squark and gluino masses, we exclude m < 260 GeV/c(2).
