Description
This presentation will summarize the results of dark matter searches
in 5 ifb of proton-proton collision data at the center-of-mass energy
7 TeV collected with the CMS detector at Large Hadron Collider (LHC)
in 2011. Dark matter particles, if produced in the collision, will be
invisible to the CMS detector; their existence can be inferred by a
large missing transverse momentum (MET). Supersymmetric (SUSY) models
predict the existence of dark matter candidate particles. This
presentation will show interpretations of the CMS SUSY searches in
terms of Constrained minimum Supersymmetric extension of the Standard
Model (CMSSM) and Simplified Model Spectra (SMS) with an emphasis on
dark matter searches. Events with large MET and a single jet (monojet
events) or events with large MET and a single photon (mono-photon
events) can be final states of direct productions of dark matter
particles after the initial-state radiation (ISR). This presentation
will also show the upper limits on the dark matter-nucleon cross
sections that the CMS monojet and mono-photon analyses placed.
