Search for top-squark pairs decaying into Higgs or Z bosons in pp collisions at √s=8 TeV
(2014-09-07)
A search for supersymmetry through the direct pair production of top squarks, with Higgs (H) or Z
bosons in the decay chain, is performed using a data sample of proton–proton collisions at √s = 8 TeV
collected in 2012 ...
Measurement of the ratio of inclusive jet cross sections using the anti- k T algorithm with radius parameters R=0.5 and 0.7 in pp collisions at s =7TeV
(2014-10-16)
Measurements of the inclusive jet cross section with the anti-kT clustering algorithm are presented for two radius parameters, R=0.5 and 0.7. They are based on data from LHC proton-proton collisions at s=7TeV corresponding ...
Differential cross section measurements for the production of a W boson in association with jets in proton-proton collisions at √s = 7 TeV
(2014-12-05)
Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse ...
Measurements of t t ̄ spin correlations and top-quark polarization using dilepton final states in pp collisions at s =7TeV
(2014-05-05)
Spin correlations and polarization in the top quark–antiquark system are measured using dilepton final states produced in pp collisions at the LHC at s√=7 TeV. The data correspond to an integrated luminosity of 5.0 fb−1 ...
Inclusive search for a vector-like T quark with charge 2/3 in pp collisions at √s=8 TeV
(2014-02-05)
A search is performed for a massive new vector-like quark T, with charge 2
3 , that is pair produced together
with its antiparticle in proton–proton collisions. The data were collected by the CMS experiment at the
Large ...
Search for top-quark partners with charge 5/3 in the same-sign dilepton final state
(2014-04-30)
A search for the production of heavy partners of the top quark with charge 5/3 is performed in events with a pair of same-sign leptons. The data sample corresponds to an integrated luminosity of 19.5fb-1 and was collected ...
Search for supersymmetry with razor variables in pp collisions at s =7TeV
(2014-12)
The razor approach to search for R-parity conserving supersymmetric particles is described in detail. Two analyses are considered: an inclusive search for new heavy particle pairs decaying to final states with at least two ...
Search for anomalous production of events with three or more leptons in pp collisions at s =8TeV
