Measurements of tt¯ spin correlations and top quark polarization using dilepton final states in pp collisions at s√=8 TeV
(American Physical Society, 2016-03)
Measurements of the top quark-antiquark (t¯t) spin correlations and the top quark polarization are presented for t¯t pairs produced in pp collisions at √s=8 TeV. The data correspond to an integrated luminosity of 19.5 fb⁻¹ ...
Measurement of the Ratio B ( B[subscript s][superscript 0] → J/ψf[subscript 0] (980))/B(B[subscript s][superscript 0] → J/ψϕ(1020)) in Pp Collisions at √s = 7 TeV
(Elsevier BV, 2016-02)
A measurement of the ratio of the branching fractions of the B[subscript s][superscript 0] meson to J/ψf0(980) and to J/ψφ(1020) is presented. The J/ψ, f[subscript 0](980), and φ(1020) are observed through their decays to ...
Measurement of inclusive jet production and nuclear modifications in pPb collisions at √SNN = 5.02 TeV
(Springer Berlin Heidelberg, 2016-07)
Inclusive jet production in pPb collisions at a nucleon–nucleon (NN) center-of-mass energy of √sNN = 5.02 TeV is studied with the CMS detector at the LHC. A data sample corresponding to an integrated luminosity of 30.1 ...
