【 摘 要 】

Various models for new physics not described by the Standard Model predict event topologies with large missing transverse energy due to invisible new particles. Such events can be identified in the detector if they are accompanied by an energetic photon or a jet with high transverse energy. This article presents results from searches for new physics with both signatures in proton-proton collision data with the ATLAS detector at the LHC. The focus is on the analyses using the full 2011 data set with an integrated luminosity of L = 4:7 fb.-1at a center of mass energy of ps = 7TeV but the article also includes an update of the monojet analysis with L = 10:5 fb.-1of data recorded in 2012 at ps = 8TeV. The results are translated into exclusion limits on parameters of difierent theoretical models.
