Measurement of top quark polarisation in t-channel single top quark production
(Springer-Verlag/SISSA, 2016-04)
A first measurement of the top quark spin asymmetry, sensitive to the top quark polarisation, in t-channel single top quark production is presented. It is based on a sample of pp collisions at a centre-of-mass energy of 8 ...
Search for two Higgs bosons in final states containing two photons and two bottom quarks in proton-proton collisions at 8 TeV
(American Physical Society, 2016-09)
A search is presented for the production of two Higgs bosons in final states containing two photons and two bottom quarks. Both resonant and nonresonant hypotheses are investigated. The analyzed data correspond to an ...
Event generator tunes obtained from underlying event and multiparton scattering measurements
(Springer-Verlag, 2016-03)
New sets of parameters (“tunes”) for the underlying-event (UE) modelling of the pythia8, pythia6 and herwig++ Monte Carlo event generators are constructed using different parton distribution functions. Combined fits to CMS ...
Measurement of the charge asymmetry in top quark pair production in pp Collisions at √s=8 TeV using a template method
(American Physical Society, 2016-02)
The charge asymmetry in the production of top quark and antiquark pairs is measured in proton-proton collisions at a center-of-mass energy of 8 TeV. The data, corresponding to an integrated luminosity of 19.6 fb⁻¹, were ...
