Search for neutral color-octet weak-triplet scalar particles in proton-proton collisions at √ s = 8 TeV
(Springer-Verlag/SISSA, 2015-09)
A search for pair production of neutral color-octet weak-triplet scalar particles (Θ[superscript 0]) is performed in processes where one Θ[superscript 0] decays to a pair of b quark jets and the other to a Z boson plus a ...
Search for supersymmetry with photons in pp collisions at √s = 8 TeV
(American Physical Society, 2015-10)
Two searches for physics beyond the standard model in events containing photons are presented. The data sample used corresponds to an integrated luminosity of 19.7 fb[superscript −1] of proton-proton collisions at √s = ...
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 ...
Search for Monotop Signatures in Proton-Proton Collisions at √s = 8 TeV
(American Physical Society, 2015-03)
Results are presented from a search for new decaying massive particles whose presence is inferred from an imbalance in transverse momentum and which are produced in association with a single top quark that decays into a ...
Search for vector-like T quarks decaying to top quarks and Higgs bosons in the all-hadronic channel using jet substructure
(Springer-Verlag, 2015-06)
A search is performed for a vector-like heavy T quark that is produced in pairs and that decays to a top quark and a Higgs boson. The data analysed correspond to an integrated luminosity of 19.7 fb[superscript −1] collected ...
Search for narrow high-mass resonances in proton–proton collisions at √s = 8 TeV decaying to a Z and a Higgs boson
(Elsevier, 2015-07)
A search for a narrow, high-mass resonance decaying into Z and Higgs (H) bosons is presented. The final state studied consists of a merged jet pair and a τ pair resulting from the decays of Z and H bosons, respectively. ...
Measurement of the top-quark mass in the t[bar over t] dilepton channel using the full CDF Run II data set
(American Physical Society, 2015-08)
We present a measurement of the top-quark mass in events containing two leptons (electrons or muons) with a large transverse momentum, two or more energetic jets, and a transverse-momentum imbalance. We use the full ...
Search for long-lived neutral particles decaying to quark-antiquark pairs in proton-proton collisions at √s = 8 TeV
(American Physical Society, 2015-01)
A search is performed for long-lived massive neutral particles decaying to quark-antiquark pairs. The experimental signature is a distinctive topology of a pair of jets, originating at a secondary vertex. Events were ...
Evidence for Collective Multiparticle Correlations in p-Pb Collisions
(American Physical Society, 2015-06)
The second-order azimuthal anisotropy Fourier harmonics, v[subscript 2], are obtained in p−Pb and PbPb collisions over a wide pseudorapidity (η) range based on correlations among six or more charged particles. The p-Pb ...
Measurement of Differential Production Cross Sections for Z/γ* Bosons in Association with Jets in p[bar over p] Collisions at √s = 1.96 TeV
(American Physical Society, 2015-01)
Differential cross sections for the production of Z bosons or off-shell photons γ[superscript *] in association with jets are measured in proton-antiproton collisions at center-of-mass energy √s = 1.96 TeV using the full ...
