three jets accompanied by large missing transverse momentum, using a data sample corresponding\ud
to an integrated luminosity of 36 pb−1 collected in proton-proton collisions at\ud
ps = 7TeV with the CMS detector at the LHC. No excess of events is observed above the\ud
expected standard model backgrounds, which are all estimated from the data. Exclusion\ud
limits are presented for the constrained minimal supersymmetric extension of the standard\ud
model. Cross section limits are also presented using simplified models with new particles\ud
decaying to an undetected particle and one or two jets.This work was supported by the Austrian Federal\ud
