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 ...

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 ...
