Measurement of the t[bar over t] Production Cross Section in the All-Jet Final State in Pp Collisions at √s =7 TeV
Chatrchyan, S.; Khachatryan, V.; Sirunyan, A. M; Tumasyan, A.; Adam, W.; e.a. (Springer-Verlag, 2013-05)A measurement is presented of the t[bar over t] production cross section (σ[subscript t[bar over t]]) in proton-proton collisions at a centre-of-mass energy of 7 TeV, in the all-jet final state that contains at least ... -
Search for exotic resonances decaying into WZ/ZZ in pp collisions at √s =7 TeV
Chatrchyan, S.; Khachatryan, V.; Sirunyan, A. M.; Tumasyan, A.; Adam, W.; e.a. (Springer-Verlag/SISSA, 2013-02)A search for new exotic particles decaying to the VZ final state is performed, where V is either a W or a Z boson decaying into two overlapping jets and the Z decays into a pair of electrons, muons or neutrinos. The analysis ... -
Search for heavy quarks decaying into a top quark and a W or Z boson using lepton + jets events in pp collisions at s√=7TeV
Chatrchyan, S.; Khachatryan, V.; Sirunyan, A. M; Tumasyan, A.; Adam, W.; e.a. (Springer-Verlag, 2013-01)Results are presented from a search for the pair-production of heavy quarks, QQ[overline appears over second Q], that decay exclusively into a top quark and a W or Z boson. The search is performed using a sample of ... -
Search for supersymmetry in final states with missing transverse energy and 0, 1, 2, or ≥3 b-quark jets in 7 TeV pp collisions using the variable α T
Chatrchyan, S.; Khachatryan, V.; Sirunyan, A. M.; Tumasyan, A.; Adam, W.; e.a. (Springer-Verlag, 2013-01)A search for supersymmetry in final states with jets and missing transverse energy is performed in pp collisions at a centre-of-mass energy of √s = 7 TeV. The data sample corresponds to an integrated luminosity of 4.98 ... -
Studies of jet mass in dijet and W/Z + jet events
Chatrchyan, S.; Khachatryan, V.; Sirunyan, A. M; Tumasyan, A.; Adam, W.; e.a. (Springer-Verlag/SISSA, 2013-05)Invariant mass spectra for jets reconstructed using the anti-kT and CambridgeAachen algorithms are studied for different jet “grooming” techniques in data corresponding to an integrated luminosity of 5 fb[superscript −1], ...
