Book Description
We report a search for diphoton events with large missing transverse energy produced in p{bar p} collisions at √s = 1.96 TeV. The data were collected with the D0 detector at the Fermilab Tevatron Collider, and correspond to 6.3 fb−1 of integrated luminosity. The observed missing transverse energy distribution is well described by the standard model prediction, and 95% C.L. limits are derived on two realizations of theories beyond the standard model. In a gauge mediated supersymmetry breaking scenario, the breaking scale [Lambda] is excluded for [Lambda]

Book Description
A search for diphoton events with large missing transverse energy produced in p{bar p} collisions at √s = 1.96 TeV is presented. The data were collected with the D0 detector at the Fermilab Tevatron Collider between 2002 and 2010, and correspond to 6.3 fb−1 of integrated luminosity. The observed missing transverse energy distribution is well described by the Standard Model prediction, and 95% C.L. limits are derived on two realizations of theories beyond the Standard Model.

Book Description
A search for diphoton events with large missing transverse energy produced in p$ar{p}$ collisions at √s = 1.96 TeV is presented. The data were collected with the D0 detector at the Fermilab Tevatron Collider between 2002 and 2010, and correspond to 6.3 fb-1 of integrated luminosity. The observed missing transverse energy distribution is well described by the Standard Model prediction, and 95% C.L. limits are derived on two realizations of theories beyond the Standard Model. In a gauge mediated supersymmetry breaking scenario, the breaking scale ? is excluded for ? 124 TeV. In a universal extra dimension model including gravitational decays, the compactification radius Rsubc/sub is excluded for Rsubc/subsup-1

Book Description
This dissertation presents the search for dark matter in events with an energetic photon and large missing transverse momentum with the ATLAS experiment at the LHC. The data of proton-proton collisions is collected in 2012 and 2015, corresponds to 20.3 fb−1 data with center-of-mass energy of 8 TeV and 3.2 fb−1data with center-of-mass energy of 13 TeV, respectively. The observed data is well described by the expected Standard Model backgrounds. The expected (observed) upper limit on the fiducial cross section for the production of events with a photon and large missing transverse momentum at 95% confidence level is 6.1 (5.3) fb with the 8 TeV data set and 25.5 (17.8) fb with the 13 TeV data set. Exclusion limits are presented on models of direct pair production of dark-matter candidates.

Book Description
The authors present the results of a search for anomalous production of diphoton events with large missing transverse energy using the Collider Detector at Fermilab. In 202 pb[sup -1] of p[bar p] collisions at [radical]s = 1.96 TeV they observe no candidate events, with an expected standard model background of 0.27 [+-] 0.07(stat) [+-] 0.10(syst) events. The results exclude a lightest chargino of mass less than 167 GeV/c[sup 2], and lightest neutralino of 93 GeV/c[sup 2] at 95% confidence level in a gauge-mediated supersymmetry-breaking model with a light gravitino.

Book Description
The authors present the results of searches for large extra dimensions in samples of events with large missing transverse energy E{sub T} and either a photon or a jet produced in p{bar p} collisions at √s = 1.96 TeV collected with the CDF II detector. For [gamma] + E{sub T} and jet + E{sub T} candidate samples corresponding to 2.0 fb−1 and 1.1 fb−1 of integrated luminosity respectively, they observe good agreement with standard model expectations and obtain a combined lower limit on the fundamental parameter of the large extra dimensions model, M{sub D}, as a function of the number of extra dimensions in the model.
