Measurement of Spin Correlation in Top Quark Pair Production in Semi-Leptonic Final State

The measurement of correlation between spins of top and anti-top quarks, produced in proton-proton collisions at LHC, is described for the semi-leptonic decay of the top quark pair (one top quark decaying leptonically and the other hadronically). The simulated events are reconstructed after full sim...

description The measurement of correlation between spins of top and anti-top quarks, produced in proton-proton collisions at LHC, is described for the semi-leptonic decay of the top quark pair (one top quark decaying leptonically and the other hadronically). The simulated events are reconstructed after full simulation of the CMS detector. The spin correlation coefficient is estimated based on a total integrated luminosity of ten inverse femtobarns. Including systematic uncertainties, the correlation coefficient can be measured with a total relative uncertainty of 17% or 27% depending on the choice of the deay angles used.
