Measurement of the mass difference between top quark and antiquark in pp collisions at s=8 TeV
(Elsevier, 2017-07-10)
The invariance of the standard model (SM) under the CPT transformation predicts equality of particle and antiparticle masses. This prediction is tested by measuring the mass difference between the top quark and antiquark ...
Measurement of the ratio B(B<inf>s</inf>0 → J/ψf<inf>0</inf>(980))/B(B<inf>s</inf>0 → J/ψφ(1020)) in pp collisions at √s=7 TeV
(Elsevier, 2016-05-10)
A measurement of the ratio of the branching fractions of the Bs0 meson to J/ψf0(980) and to J/ψφ(1020) is presented. The J/ψ, f0(980), and φ(1020) are observed through their decays to μ+μ-, π+π-, and K+K-, respectively. ...
Observation of the rare Bs0 →µ+µ− decay from the combined analysis of CMS and LHCb data
(Macmillan Publishers, 2015-06-04)
The standard model of particle physics describes the fundamental particles and their interactions via the strong, electromagnetic and weak forces. It provides precise predictions for measurable quantities that can be tested ...
Search for supersymmetry in pp collisions at root s=8 TeV in events with a single lepton, large jet multiplicity, and multiple b jets
(Elsevier, 2014)
Results are reported from a search for supersymmetry in pp collisions at a center-of-mass energy of 8 TeV, based on events with a single isolated lepton (electron or muon) and multiple jets, at least two of which are ...
Search for supersymmetry in pp collisions at s =8 TeV in final states with boosted W bosons and b jets using razor variables
(American Physical Society, 2016-05-01)
A search for supersymmetry in hadronic final states with highly boosted W bosons and b jets is presented, focusing on compressed scenarios. The search is performed using proton-proton collision data at a center-of-mass ...
Measurement of the inclusive 3-jet production differential cross section in proton-proton collisions at 7 TeV and determination of the strong coupling constant in the TeV range
(Springer Nature, 2015-05)
This paper presents a measurement of the inclusive 3-jet production differential cross section at a proton–proton centre-of-mass energy of 7 TeV using data corresponding to an integrated luminosity of 5 fb−1fb−1 collected ...
Search for supersymmetry using razor variables in events with b-tagged jets in pp collisions at root s=8 TeV
(2015-03-01)
An inclusive search for supersymmetry in events with at least one b-tagged jet is performed using proton-proton collision data collected by the CMS experiment in 2012 at a center-of-mass energy of 8 TeV. The data set size ...
Performance of electron reconstruction and selection with the CMS detector in proton-proton collisions at root s=8 TeV
(IOP Publishing, 2015-06)
The performance and strategies used in electron reconstruction and selection at CMS are presented based on data corresponding to an integrated luminosity of 19.7 fb−1, collected in proton-proton collisions at √s = 8 TeV ...
Measurements of jet multiplicity and differential production cross sections of Z plus jets events in proton-proton collisions at root s=7 TeV
(American Physical Society, 2015-03-01)
Measurements of differential cross sections are presented for the production of a Z boson and at least one hadronic jet in proton-proton collisions at s√=7 TeV, recorded by the CMS detector, using a data sample corresponding ...
Search for decays of stopped long-lived particles produced in proton-proton collisions at root s=8TeV
(Springer Nature, 2015-04)
A search has been performed for long-lived particles that could have come to rest within the CMS detector, using the time intervals between LHC beam crossings. The existence of such particles could be deduced from observation ...
