Measurements of the tt¯ production cross section in lepton+jets final states in pp collisions at 8 TeV and ratio of 8 to 7 TeV cross sections

Khachatryan, V.; Sirunyan, A.M.; Tumasyan, A; Baarmand, M.M.; Colafranceschi, Stefano; Bhopatkar, Vallary; Hohlmann, Marcus; Roy, Tuhin S.; Noonan, D.; Yumiceva, Francisco X. (2017-01-07)

A measurement of the top quark pair production (tt¯) cross section in proton–proton collisions at the centre-of-mass energy of 8TeV is presented using data collected with the CMS detector at the LHC, corresponding to an ...
Search for supersymmetry in electroweak production with photons and large missing transverse energy in pp collisions at √s=8TeV

Khachatryan, V.; Sirunyan, A.M.; Tumasyan, A; Roy, Tuhin S.; Baarmand, M.M.; Noonan, D.; Bhopatkar, Vallary; Colafranceschi, Stefano; Hohlmann, Marcus; Yumiceva, Francisco X. (2016-08-10)

Results are reported from a search for supersymmetry with gauge-mediated supersymmetry breaking in electroweak production. Final states with photons and large missing transverse energy ( ET miss) were examined. The data ...
