Search for Narrow Resonances in the b -Tagged Dijet Mass Spectrum in Proton-Proton Collisions at √s = 8 TeV
(American Physical Society, 2018-05-31)
A search for narrow resonances decaying to bottom quark-antiquark pairs is presented, using a data sample of proton-proton collisions at √s=8 TeV corresponding to an integrated luminosity of 19.7 fb[superscript −1]. The ...
Measurement of the W boson helicity in events with a single reconstructed top quark in pp collisions at √s = 8 TeV
(Springer-Verlag, 2015-01)
A measurement of the W boson helicity is presented, where the W boson originates from the decay of a top quark produced in pp collisions. The event selection, optimized for reconstructing a single top quark in the final ...
Measurements of the Differential Jet Cross Section as a Function of the Jet Mass in Dijet Events from Proton-Proton Collisions at √s = 13 TeV
(Springer Nature, 2018-11)
Measurements of the differential jet cross section are presented as a function of the jet mass in dijet events, in bins of jet transverse momentum, with and without a jet grooming algorithm. The data have been recorded by ...
Measurement of the W[superscript +]W[superscript −] √ and ZZ production cross sections in pp collisions at √s = 8 TeV
(Elsevier BV, 2013-03)
The W[superscript +]W[superscript −] and ZZ production cross sections are measured in proton-proton collisions at √s=8TeV with the CMS experiment at the LHC in data samples corresponding to an integrated luminosity of up ...
Effectiveness of flipped classroom techniques in an advanced laboratory physics course
(American Association of Physics Teachers, 2015-11-17)
We report preliminary observations of changes in responses to student surveys over a five year period in an advanced laboratory course for third-year physics majors at the Massachusetts Institute of Technology. This period ...
Multiplicity and transverse momentum dependence of two- and four-particle correlations in pPb and PbPb collisions
(Elsevier, 2013-06)
Measurements of two- and four-particle angular correlations for charged particles emitted in pPb collisions are presented over a wide range in pseudorapidity and full azimuth. The data, corresponding to an integrated ...
Search for vector-like T quarks decaying to top quarks and Higgs bosons in the all-hadronic channel using jet substructure
(Springer-Verlag, 2015-06)
A search is performed for a vector-like heavy T quark that is produced in pairs and that decays to a top quark and a Higgs boson. The data analysed correspond to an integrated luminosity of 19.7 fb[superscript −1] collected ...
Search for physics beyond the standard model in high-mass diphoton events from proton-proton collisions at
(American Physical Society, 2018-11)
A search for physics beyond the standard model is performed using a sample of high-mass diphoton events produced in proton-proton collisions at √s=13 TeV. The data sample was collected in 2016 with the CMS detector at 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)
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[superscript −1] collected with the CMS detector. ...
Search for long-lived particles that decay into final states containing two electrons or two muons in proton-proton collisions at √s = 8 TeV
(American Physical Society, 2015-03)
A search is performed for long-lived particles that decay into final states that include a pair of electrons or a pair of muons. The experimental signature is a distinctive topology consisting of a pair of charged leptons ...
