Search for supersymmetry in events with a Z boson, jets and missing energy using the JZB method

A search is presented for physics beyond the standard model (BSM) in events with a $Z$ boson, jets, and missing transverse energy \n($E_{T}^{miss}$). This signature is motivated by BSM physics scenarios, including supersymmetry.\nThe study is performed using a sample of proton-proton collision data collected at $\\sqrt{s}=7$~TeV with the\nCMS experiment at the LHC, corresponding to an integrated luminosity of 4.98~fb${}^{-1}$.\nThe contributions from the dominant standard model backgrounds are estimated from data using the jet-Z balance technique.\nIn the absence of evidence for BSM physics, we \ninterpret the results in the context of simplified model spectra.
