Top-Quark Mass Measurement Using Events with Missing Transverse Energy and Jets at CDF
(American Physical Society (APS), 2011-11)
We present a measurement of the top-quark mass using a sample of tt̅ events in 5.7 fb[superscript -1] of integrated luminosity from pp̅ collisions at the Fermilab Tevatron with √s=1.96 TeV and collected by the CDF II ...
Measurement of the B[± over c] production cross section in p[bar over p] collisions at √s = 1.96 TeV
(American Physical Society, 2016-03)
We describe a measurement of the ratio of the cross sections times branching fractions of the B[+ over c] meson in the decay mode B[+ over c] → J/ψμ[superscript +]ν to the B[superscript +] meson in the decay mode B[superscript ...
Search for New Physics with a Dijet Plus Missing ET Signature in pp̅ Collisions at √s=1.96 TeV
(American Physical Society, 2010-09)
We present results of a signature-based search for new physics using a dijet plus missing transverse energy (E[subscript T]T) data sample collected in 2 fb[superscript -1] of pp̅ collisions at √s=1.96 TeV with the CDF ...
Search for Dark Matter Produced with an Energetic Jet or a Hadronically Decaying W or Z Boson at √s = 13 TeV
(Springer Berlin Heidelberg, 2017-07)
A search for dark matter particles is performed using events with large missing transverse momentum, at least one energetic jet, and no leptons, in proton-proton collisions at √s = 13 TeV collected with the CMS detector ...
Measurement of the W boson helicity in events with a single reconstructed top quark in pp collisions at √s = 8 TeV
(Springer-Verlag, 2015-01)
A measurement of the W boson helicity is presented, where the W boson originates from the decay of a top quark produced in pp collisions. The event selection, optimized for reconstructing a single top quark in the final ...
Searches for Invisible Decays of the Higgs Boson in pp Collisions at √s = 7, 8, and 13 TeV
(Springer Nature, 2017-02)
Searches for invisible decays of the Higgs boson are presented. The data collected with the CMS detector at the LHC correspond to integrated luminosities of 5.1, 19.7, and 2.3 fb⁻¹ at centre-of-mass energies of 7, 8, and ...
Constraints on the double-parton scattering cross section from same-sign W boson pair production in proton-proton collisions at √s = 8 TeV
(Springer International Publishing AG, 2018-02)
A first search for same-sign WW production via double-parton scattering is performed based on proton-proton collision data at a center-of-mass energy of 8 TeV using dimuon and electron-muon final states. The search is based ...
Measurement of the inclusive t[bar over t] cross section in pp collisions at √s = 5.02 TeV using final states with at least one charged lepton
(Springer Berlin Heidelberg, 2018-03)
The top quark pair production cross section (σ[subscript t[bar over t]]) is measured for the first time in pp collisions at a center-of-mass energy of 5.02 TeV. The data were collected by the CMS experiment at the LHC and ...
Search for a heavy vector boson decaying to two gluons in pp̅ collisions at √s=1.96 TeV
(American Physical Society, 2012-12)
We present a search for a new heavy vector boson Z[superscript ′] that decays to gluons. Decays to on-shell gluons are suppressed, leading to a dominant decay mode of Z[superscript ′]→g[superscript *]g. We study the case ...
Measurement of the B[subscript c][superscript -] meson lifetime in the decay B[subscript c][superscript -] →J/ψπ[superscript -]
(American Physical Society, 2013-01)
The lifetime of the B[subscript c][superscript -] meson is measured using 272 exclusive B[subscript c][superscript -]→J/ψ(→μ[superscript +]μ[superscript -])π[superscript -] decays reconstructed in data from proton-antiproton ...
