Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb −1−1  of  s√=8s=8  TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with  pT>120pT>120  GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between  EmissT>150ETmiss>150  GeV and  EmissT>700ETmiss>700  GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presented.
