(2015-01-07)
Erratum to: JHEP01(2014)163. The online version of the original article can be found at http://dx.doi.org/10.1007/JHEP01(2014)16
Search for anomalous tt̄ production in the highly-boosted all-hadronic final stat
(2012-09-11)
A search is presented for a massive particle, generically referred to as a Z′, decaying into a tt¯ pair. The search focuses on Z′ resonances that are sufficiently massive to produce highly Lorentz-boosted top quarks, which ...
Comparison of the Z/γ ∗ + jets to γ + jets cross sections in pp collisions at √s = 8 TeV
(2015-10-20)
A comparison of the differential cross sections for the processes Z/γ * + jets and photon (γ)+jets is presented. The measurements are based on data collected with the CMS detector at √s = 8 TeV corresponding to an integrated ...
Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at √s = 8 TeV
(2014-06-10)
A search for new physics is performed in multijet events with large missing transverse momentum produced in proton-proton collisions at √s = 8 TeV using a data sample corresponding to an integrated luminosity of 19.5 fb−1 ...
Search for physics beyond the standard model in events with two leptons, jets, and missing transverse momentum in pp collisions at √s = 8 TeV
(2015-04-22)
A search is presented for physics beyond the standard model in final states with two opposite-sign same-flavor leptons, jets, and missing transverse momentum. The data sample corresponds to an integrated luminosity of 19.4 ...
Search for a fermiophobic Higgs boson in pp collisions at √s = 7 TeV
(2012-09-25)
Combined results are reported from searches for a fermiophobic Higgs boson in the γγ, WW, and ZZ decay modes in proton-proton collisions at √s = 7 TeV. The explored Higgs boson mass range is 110–300 GeV. The data sample ...
Measurement of prompt J/ψ pair production in pp collisions at √s = 7 Tev
(2014-09-17)
Production of prompt J/ψ meson pairs in proton-proton collisions at √s = 7 TeV is measured with the CMS experiment at the LHC in a data sample corresponding to an integrated luminosity of about 4.7 fb−1. The two J/ψ ...
Measurement of the underlying event activity using charged-particle jets in proton-proton collisions at √s = 2.76 TeV
(2015-09-21)
A measurement of the underlying event (UE) activity in proton-proton collisions
is performed using events with charged-particle jets produced in the central pseudorapidity
region (|η
jet| < 2) and with transverse momentum ...
