Erratum: supersymmetric monojets at the Large Hadron Collider

Abstract

Supersymmetric monojets may be produced at the Large Hadron Collider by the process $ qg \to \tilde{q}\tilde{\chi }_1^0 \to \tilde{q}\tilde{\chi }_1^0\tilde{\chi }_1^0 $ , 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 $ \tilde{\chi }_1^0\tilde{q}q $ coupling via the rate for monojet events. Such a coupling contains information on the composition of the $ \tilde{\chi }_1^0 $ and helps bound dark matter direct detection cross-sections and the dark matter relic density of the $ \tilde{\chi }_1^0 $ . It also provides a check of the supersymmetric relation between gauge couplings and gaugino-quark-squark couplings.
