Measurement of four-jet production in proton-proton collisions at root s=7 TeV
(American Physical Society, 2014-05-01)
Measurements of the differential cross sections for the production of exactly four jets in proton-proton collisions are presented as a function of the transverse momentum p(T) and pseudorapidity eta, together with the ...
Jet and underlying event properties as a function of charged-particle multiplicity in proton–proton collisions at TeX
(Springer Science+Business Media, 2013-12)
Characteristics of multi-particle production in proton-proton collisions at root s = 7 TeV are studied as a function of the charged-particle multiplicity, N (ch). The produced particles are separated into two classes: those ...
Measurements of t¯tH production and the CP structure of the Yukawa interaction between the Higgs Boson and top quark in the diphoton decay channel
(American Physical Society, 2020-08-05)
The first observation of the (tt) over barH process in a single Higgs boson decay channel with the full reconstruction of the final state (H -> gamma gamma) is presented, with a significance of 6.6 standard deviations ...
Search for new physics with long-lived particles decaying to photons and missing energy in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2012-11)
A search is performed for long-lived neutral particles decaying into a photon and invisible particles. An example of such a signature is the decay of the lightest neutralino with nonzero lifetime into a gravitino and a ...
Measurement of the triple-differential cross section for photon plus jets production in proton-proton collisions at=7 TeV
(Springer Science+Business Media, 2014-06)
A measurement of the triple-differential cross section, , in photon + jets final states using a data sample from proton-proton collisions at = 7 TeV is presented. This sample corresponds to an integrated luminosity of 2.14 ...
Measurements of the ϒ(1S), ϒ(2S), and ϒ(3S) differential cross sections in pp collisions at s=7TeV
(Elsevier, 2015-10-07)
Differential cross sections as a function of transverse momentum pT are presented for the production of ϒ(nS) (n = 1, 2, 3) states decaying into a pair of muons. Data corresponding to an integrated luminosity of 4.9View ...
Constraints on the pMSSM, AMSB model and on other models from the search for long-lived charged particles in proton–proton collisions at s√=8TeV
(Springer, 2015-07-15)
Stringent limits are set on the long-lived lepton-like sector of the phenomenological minimal supersymmetric standard model (pMSSM) and the anomaly-mediated supersymmetry breaking (AMSB) model. The limits are derived from ...
Search for top squarks decaying via four-body or chargino-mediated modes in single-lepton final states in proton-proton collisions at √s=13 TeV
(Springer Nature, 2018-09)
A search for the pair production of the lightest supersymmetric partner of the top quark ((t) over tilde (1)) is presented. The search focuses on a compressed scenario where the mass difference between the top squark and ...
A measurement of the Higgs boson mass in the diphoton decay channel
(Springer Nature, 2020-06-10)
A measurement of the mass of the Higgs boson in the diphoton decay channel is presented. This analysis is based on 35.9 fb(-1) of proton-proton collision data collected during the 2016 LHC running period, with the CMS ...
Determination of the top-quark pole mass and strong coupling constant from the tt production cross section in pp collisions at root s=7 TeV
(Elsevier, 2014-01-20)
The inclusive cross section for top-quark pair production measured by the CMS experiment in proton–proton collisions at a center-of-mass energy of 7 TeV is compared to the QCD prediction at next-to-next-to-leading order ...
