MISSING TRANSVERSE ENERGY MEASUREMENT IN ATLAS DETECTOR:FIRST LHC DATA RESULTS AND IMPORTANCE FOR PHYSICS STUDY
… end of November 2009, first at a centre-of-mass energy of 900 GeV, then, since March 2010, at 7 TeV. During this period the ATLAS experiment has collected a large number of proton-proton collision events, resulting up to now in an integrated luminosity of about 45 pb−1 . miss A very good …

Searches for supersymmetric particles in events with two opposite-sign same-flavor leptons, jets, and large missing transverse energy
… channel. The SUSY analyses usually require large missing transverse energy MET for the presence of invisible LSPs. One of the most difficult background processes to estimate in these searches is due to artificial MET from hadronic object (jet) energy mismeasurements, which are difficult to model …

Search for Long-Lived Neutral Particles in Final States with Delayed Photon and Missing Transverse Energy from Proton-Proton Collisions Using the CMS detector.
… in final state with delayed photons and large missing transverse energy produced in LHC proton-proton collisions at center-of-mass energy, $\sqrt{s} = 8$TeV. Capitalizing on the excellent timing resolution of the CMS Electromagnetic Calorimeter the search uses photon time measurements made by …

Search for Excited Randall-Sundrum Gravitons with Semi-Leptonic Diboson Final States in 4.7 fb-1 of Proton-Proton Collisions using the ATLAS Detector at the Large Hadron Collider
… a single charged lepton, at least two jets and missing transverse energy are analyzed and no significant deviation from the Standard Model prediction is observed. Upper limits on the production cross section are interpreted as lower limits on the mass of a resonance and are derived assuming two …

Search for supersymmetry in opposite sign dilepton final states with the CMS experiment
… lepton pairs accompanied by hadronic jets and missing transverse energy is presented. This signature is a typical signature in many supersymmetric models. In a study based on simulation the discovery potential and possible parameter extraction of a specific supersymmetric model is evaluated. …

Measurement of the single top quark cross section in the lepton plus jets final state in proton-antiproton collisions at a center of mass energy of 1.96 TeV using the CDF II detector.
… by the signature of a charged lepton, large missing transverse energy, and two or three jets with at least one of them identified as originating from a bottom quark. A new Monte Carlo generator powheg is used to model the single top quark production processes, which include s-channel, …

Study of the Higgs Boson Produced in Association with a Weak Boson and Decaying to WW* with a Same Sign Dilepton and Jets Final State in √ s =8 TeV pp Collisions with the ATLAS Detector at the LHC
… hadronically, giving two leptons, jets, and missing transverse energy as the final state signature in the ATLAS detector. The two leptons are required to have the same sign charge in order to suppress the many Standard Model background processes with oppositely charged di-lepton final states. …

Suppression of the fake lepton background in same-sign W-boson scattering with the ATLAS experiment
… of two same-sign leptons, two forward jets, and missing transverse energy carried away by two neutrinos. Non-prompt leptons are defined as leptons coming from the decay of hadrons. Such leptons, together with jets misreconstructed as leptons, contribute to the background processes in same-sign …

Searches for Vector Like Quarks Decaying to Ht, Zt, or Wt in the Single Lepton Channel with the ATLAS Detector
… least one originates from a b-quark, and large missing transverse energy are selected. Data was collected from proton-proton collisions at center of mass energy sqrt(s)=13 TeV and integrated luminosity of 139 fb -1 representing the full LHC Run 2 dataset, using the ATLAS detector. This search …

Searching for long-lived particles Beyond the Standard Model with displaced vertex signatures using the ATLAS detector: Not all hopes for new physics die immediately
… analysis uses a similar strategy, but using missing transverse energy as the trigger. This improves upon the early Run 2 2016-data search with an updated analysis strategy and a new vertexing algorithm. A focus on interpreting this search with the the Higgs Portal model predicts sensitivity …
