Measurement of the electroweak top quark production cross section and the CKM matrix element V (tb) with the DO experiment
… of the combined s+t-channel electroweak topquark production cross section at the Tevatron collider. An integrated luminosity of nearly 1 fb^{-1} of Run~II data has been analyzed. After the selection of single top quark-like events, a Multi-Process Factory hasbeen used to analyze each event under …

Development of the detector control system for the ATLAS Level-1 trigger and measurement of the single top production cross section
… discovery potential for electroweak single top production during early running. Using Monte Carlo data some of the major systematics are discussed. A potential upper limit on the production cross section is calculated to be 45.2 pb. If the Standard Model prediction is assumed, a measured signal …

Placing limits on the Higgs production cross section at the tevatron using the H to W+W- to l+l- decay channel
Limits on the Higgs production crosssection at the Tevatron were placed using data with an integrated luminosity of 2.4 fb−1 from CDF. Limits over a Higgs mass range between 110 GeV and 200 GeV were determined, by calculating a limit at ten mass points distributed over this region. The analysis …

Measurement of the top anti-top quark pair production cross section in the dilepton decay channel using Lepton+Track selection in 7 TeV p − p collisions with L = 698 PB−1
We present measurements of the t¯t production cross section obtained using the ATLAS detector at the LHC with pp collisions at √s = 7 TeV in dilepton final states, from a data sample of L=698 pb−1 taken in 2011. For dilepton pair selection we have used a ‘Lepton+Track’ approach, where selection …

Exclusive search for Higgs boson to gamma-gamma decay via vector boson fusion production mechanism
… the vector boson fusion process. The theoretical production cross section limit is analyzed over the accepted possible mass range for the Higgs boson, 120-130 GeV/c 2 . We are able to reduce the theoretical production cross section limit to ~ 6[sigma]SM in this range by using a boosted decision …
