Measurement of the differential cross section for top quark pair production in pp collisions at √s = 8 TeV
(2015)The European Physical Journal CThe normalized differential cross section for top quark pair (tt¯) production is measured in pp collisions at a centre-of-mass energy of 8TeV at the CERN LHC using the CMS detector in data corresponding to an integrated luminosity of 19.7fb−1. The measurements are performed in the lepton+jets (e/μ +jets) and in the dilepton (e+e−, μ+μ−, and e±μ∓) decay channels. The tt¯ cross section is measured as a function of the kinematic properties ...Journal Article -
Search for a charged Higgs boson in pp collisions at √s =8 TeV
(2015)Journal of High Energy PhysicsA search for a charged Higgs boson is performed with a data sample corresponding to an integrated luminosity of 19.7 ± 0.5 fb−1 collected with the CMS detector in proton-proton collisions at s√=8,TeV. The charged Higgs boson is searched for in top quark decays for m H± < m t − m b, and in the direct production pp → t(b)H± for m H± > m t − m b. The H± → τ ± ν τ and H± → tb decay modes in the final states τ h+jets, μτ h, ℓ+jets, and ℓℓ’ (ℓ ...Journal Article -
Constraints on parton distribution functions and extraction of the strong coupling constant from the inclusive jet cross section in pp collisions at √s = 7 TeV
(2015)The European Physical Journal CThe inclusive jet cross section for proton–proton collisions at a centre-of-mass energy of 7TeV was measured by the CMS Collaboration at the LHC with data corresponding to an integrated luminosity of 5.0fb−1. The measurement covers a phase space up to 2TeV in jet transverse momentum and 2.5 in absolute jet rapidity. The statistical precision of these data leads to stringent constraints on the parton distribution functions of the proton. ...Journal Article -
Measurement of the inclusive 3-jet production differential cross section in proton–proton collisions at 7 TeV and determination of the strong coupling constant in the TeV range
(2015)The European Physical Journal CThis paper presents a measurement of the inclusive 3-jet production differential cross section at a proton–proton centre-of-mass energy of 7 TeV using data corresponding to an integrated luminosity of 5fb−1collected with the CMS detector. The analysis is based on the three jets with the highest transverse momenta. The cross section is measured as a function of the invariant mass of the three jets in a range of 445–3270 GeV and in two bins ...Journal Article -

Measurement of electroweak production of two jets in association with a Z boson in proton–proton collisions at √s=8TeV
(2015)The European Physical Journal CThe purely electroweak (EW) cross section for the production of two jets in association with a Z boson, in proton–proton collisions at s√=8TeV, is measured using data recorded by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 19.7fb-1. The electroweak cross section for the ℓℓjj final state (with ℓ=e or μ and j representing the quarks produced in the hard interaction) in the kinematic region defined by ...Journal Article
