Measurement of the X(3872) production cross section via decays to J/ψπ+π− in pp collisions at √s = 7 TeV
(2013-04-29)
The production of the X(3872) is studied in pp collisions at √s = 7 TeV, using decays to J/ψπ+π−, where the J/ψ decays to two muons. The data were recorded by the CMS experiment and correspond to an integrated luminosity ...
Measurement of the λb 0 lifetime in pp collisions at √s = 7 TeV
(2013-07-26)
A measurement of the Λ0b lifetime using the decay Λ0b→J/ψΛ in protonproton collisions at √s = 7 TeV is presented. The data set, corresponding to an integrated luminosity of about 5 fb−1, was recorded with the CMS experiment ...

(2013-05-28)
A search for the standard model Higgs boson produced in association with a top-quark pair is presented using data samples corresponding to an integrated luminosity of 5.0 fb−1 (5.1 fb−1) collected in pp collisions at the ...
Search for new physics in events with same-sign dileptons and b jets in pp collisions at √s = 8 TeV
(2013-03-06)
A search for new physics is performed using events with isolated same-sign leptons and at least two bottom-quark jets in the final state. Results are based on a sample of proton-proton collisions collected at a center-of-mass ...
Study of exclusive two-photon production of W+W- in pp collisions at √s=7 TeV and constraints on anomalous quartic gauge couplings
(2013-07-18)
A search for exclusive or quasi-exclusive W+W− production by photon-photon interactions, pp → p(*)W+W−p(*), at √s = 7 TeV is reported using data collected by the CMS detector with an integrated luminosity of 5.05 fb−1. ...
Observation of a new boson with mass near 125 GeV in pp collisions at √s = 7 and 8 TeV
(2013-06-20)
A detailed description is reported of the analysis used by the CMS Collaboration in the search for the standard model Higgs boson in pp collisions at the LHC, which led to the observation of a new boson. The data sample ...
Studies of jet mass in dijet and W/Z + jet events
(2013-05-17)
Invariant mass spectra for jets reconstructed using the anti-kT and CambridgeAachen algorithms are studied for different jet “grooming” techniques in data corresponding to an integrated luminosity of 5 fb−1, recorded with ...
Measurement of the hadronic activity in events with a Z and two jets and extraction of the cross section for the electroweak production of a Z with two jets in pp collisions at √s = 7 TeV
(2013-10-10)
The first measurement of the electroweak production cross section of a Z boson with two jets (Zjj) in pp collisions at √s 7 TeV is presented, based on a data sample recorded by the CMS experiment at the LHC with an integrated ...
Search in leptonic channels for heavy resonances decaying to long-lived neutral particles
(2013-02-14)
A search is performed for heavy resonances decaying to two long-lived massive neutral particles, each decaying to leptons. The experimental signature is a distinctive topology consisting of a pair of oppositely charged ...
Measurement of the cross section and angular correlations for associated production of a Z boson with b hadrons in pp collisions at √s = 7 TeV
(2013-12-06)
A study of proton-proton collisions in which two b hadrons are produced in association with a Z boson is reported. The collisions were recorded at a centre-of-mass energy of 7 TeV with the CMS detector at the LHC, for an ...
