摘要：

Supersymmetric monojets may be produced at the Large Hadron Collider by the process qg -> (q) over tilde(chi) over tilde (0)(1) -> q (chi) over tilde (0)(1)(chi) over tilde (0)(1) , leading to a jet recoiling against missing transverse momentum. We discuss the feasibility and utility of the supersymmetric monojet signal. In particular, we examine the possible precision with which one can ascertain the (chi) over tilde (0)(1)(q) over tilde coupling via the rate for monojet events. Such a coupling contains information on the composition of the (chi) over tilde (0)(1) and helps bound dark matter direct detection cross-sections and the dark matter relic density of the (q) over tilde (0)(1). It also provides a check of the supersymmetric relation between gauge couplings and gaugino-quark-squark couplings.
