Supersymmetric monojets at the Large Hadron Collider

Abstract

Supersymmetric monojets may be produced at the Large Hadron Collider by the process qg → q̃χ̃01 → qχ̃01χ01, 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 χq̃q coupling via the rate for monojet events. Such a coupling contains information on the composition of the χ̃01 and helps bound dark matter direct detection cross-sections and the dark matter relic density of the χ̃01. It also provides a check of the supersymmetric relation between gauge couplings and gaugino-quark-squark couplings. © SISSA 2011.
