Description
In proton-proton collisions at the LHC, pairs of top and anti-top quarks are expected to be
mostly produced through gluon fusion. Making use of the large number of top quark pairs collected,
we present measurements of the spin correlation between top and anti-top quarks using several variables
and discuss their sensitivity to new physics. In addition, we present measurements of the top quark
polarisation predicted in models with CP-conserving and CP-violating processes.
