Abstract (data abstract)
CERN-LHC. Measurements of the charge asymmetry in top quark production using the electron+jets and muon+jets decay channels in proton-proton collisions at a centre-of-mass energy of 8 TeV with 19.8/fb of data collected in 2012. Measurements are performed with extrapolations both to the full phase space or to a fiducial phase space. The fiducial region is defined as: - 4 particle-level jets of at least 30 GeV within $|\eta| < 2.5$, clustered with the anti-kT algorithm with a resolution parameter of 0.5. Theoretical calculations should perform a clustering of the produced partons with the same parameters in order to emulate the particle-level jets used in the analysis. - One electron or muon of $p_\text{T} > 30 \, (27) \, \text{GeV}$ within $|\eta| < 2.5 \,(2.1)$. - Reject events with an additional electron or muon of $p_\text{T} > 20 \, (10) \, \text{GeV}$ within $|\eta| < 2.5 \,(2.5)$. - Reject events where the axis of one of the clustered jets/partons has an angular separation of $\Delta R < 0.4$ to the lepton, with $\Delta R = \sqrt{ (\Delta \eta)^2 + (\Delta \phi)^2 }$.
