Measurement of the W+W− cross section in pp collisions at $\sqrt{s} = 7\mbox{ TeV}$ and limits on anomalous WWγ and WWZ couplings
(Springer Berlin Heidelberg, 2013-10)
A measurement of W+W− production in pp collisions at √s = 7 TeV is presented. The data were collected with the CMS detector at the LHC, and correspond to an in- tegrated luminosity of 4.92 ± 0.11 fb−¹. The W+W− candidates ...
Event Shapes and Azimuthal Correlations in Z+jets Events in Pp Collisions at √S=7 TeV
(Elsevier BV, 2013-05)
Measurements of event shapes and azimuthal correlations are presented for events where a Z boson is produced in association with jets in proton-proton collisions. The data collected with the CMS detector at the CERN LHC ...
Measurement of the ratio of the inclusive 3-jet cross section to the inclusive 2-jet cross section in pp collisions at √s = 7 TeV and first determination of the strong coupling constant in the TeV range
(Springer-Verlag, 2013-10)
A measurement is presented of the ratio of the inclusive 3-jet cross section to the inclusive 2-jet cross section as a function of the average transverse momentum, ⟨p[subscript T1,2]⟩, of the two leading jets in the event. ...
Search for fractionally charged particles in pp collisions at √s=7 TeV
(American Physical Society, 2013-05)
A search is presented for free heavy long-lived fractionally charged particles produced in pp collisions at √s=7 TeV. The data sample was recorded by the CMS detector at the LHC and corresponds to an integrated luminosity ...
Study of the underlying event at forward rapidity in pp collisions at √s=0.9,2.76, and 7 TeV
(Springer Science and Business Media LLC, 2013)
© 2013, CERN. The underlying event activity in proton-proton collisions at forward pseudo-rapidity (—6.6 < η < —5.2) is studied with the CMS detector at the LHC, using a novel observable: the ratio of the forward energy ...
Search for flavor changing neutral currents in top quark decays in pp collisions at 7 TeV
(Elsevier BV, 2013)
The results of a search for flavor changing neutral currents in top quark decays t→Zq in events with a topology compatible with the decay chain tt̄→Wb+Zq→ℓνb+ℓℓq are presented. The search is performed with a data sample ...
Search for heavy quarks decaying into a top quark and a W or Z boson using lepton + jets events in pp collisions at s√=7TeV
(Springer-Verlag, 2013-01)
Results are presented from a search for the pair-production of heavy quarks, QQ[overline appears over second Q], that decay exclusively into a top quark and a W or Z boson. The search is performed using a sample of ...
Measurement of the elliptic anisotropy of charged particles produced in PbPb collisions at √sNN=2.76 TeV
(American Physical Society, 2013-01)
The anisotropy of the azimuthal distributions of charged particles produced in [√ over s[subscript NN]]=2.76 TeV PbPb collisions is studied with the CMS experiment at the LHC. The elliptic anisotropy parameter, v[subscript ...
