Limits on the Higgs boson lifetime and width from its decay to four charged leptons
(American Physical Society, 2015-10-01)
Constraints on the lifetime and width of the Higgs boson are obtained from H→ZZ→4ℓ events using data recorded by the CMS experiment during the LHC run 1 with an integrated luminosity of 5.1 and 19.7 fb−1 at a center-of-mass ...
Measurement of the differential cross section for top quark pair production in pp collisions at root s=8TeV
(Springer Nature, 2015-11)
The normalized differential cross section for top quark pair ( tt¯tt¯ ) production is measured in pp collisions at a centre-of-mass energy of 8 TeVTeV at the CERN LHC using the CMS detector in data corresponding to an ...
Search for dark matter, extra dimensions, and unparticles in monojet events in proton-proton collisions at root s=8TeV
(Springer Nature, 2015-05)
Results are presented from a search for particle dark matter (DM), extra dimensions, and unparticles using events containing a jet and an imbalance in transverse momentum. The data were collected by the CMS detector in ...
Comparison of the Z/γ ∗ + jets to γ + jets cross sections in pp collisions at = 8 TeV
(Springer International Publishing, 2015-10)
A comparison of the differential cross sections for the processes Z/γ * + jets and photon (γ)+jets is presented. The measurements are based on data collected with the CMS detector at s√=8s=8 TeV corresponding to an ...
Evidence for collective multiparticle correlations in p-Pb collisions
(American Physical Society, 2015-07-03)
The second-order azimuthal anisotropy Fourier harmonics, v2, 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 data, corresponding ...

(Elsevier, 2015-06-30)
The first measurement of the cross section ratio View the MathML source is presented using a data sample corresponding to an integrated luminosity of 19.6 fb−1 collected in pp collisions at View the MathML source with the ...
Study of vector boson scattering and search for new physics in events with two same-sign leptons and two jets
(American Physical Society, 2015-02-06)
A study of vector boson scattering in pp collisions at a center-of-mass energy of 8 TeV is presented. The data sample corresponds to an integrated luminosity of 19.4 fb−1 collected with the CMS detector. Candidate events ...
Measurement of the ratio of the production cross sections times branching fractions of B c ± → J/ψπ ± and B± → J/ψK ± and B(B±c→J/ψπ±π±π∓)/B(B±c→J/ψπ±)B(Bc±→J/ψπ±π±π∓)/B(Bc±→J/ψπ±) in pp collisions at s√=7s=7 TeV

The ratio of the production cross sections times branching fractions (σ(B±c)B(B±c→J/ψπ±))/(σ(B±)B(B±→J/ψK±))(σ(Bc±)B(Bc±→J/ψπ±))/(σ(B±)B(B±→J/ψK±)) is studied in proton-proton collisions at a center-of-mass energy of 7 ...
Performance of the CMS missing transverse momentum reconstruction in pp data at root s=8 TeV
(IOP Publishing, 2015-02)
The performance of missing transverse energy reconstruction algorithms is presented using √s=8 TeV proton-proton (pp) data collected with the CMS detector. Events with anomalous missing transverse energy are studied, and ...
Search for long-lived neutral particles decaying to quark-antiquark pairs in proton-proton collisions at root s=8 TeV
(American Physical Society, 2015-01-01)
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 ...
