Search for CP violation in tt¯ production and decay in proton-proton collisions at √s=8 TeV

: The results of a first search for CP violation in the production and decay of top quark-antiquark (tt¯) pairs are presented. The search is based on asymmetries in T-odd, triple-product correlation observables, where T is the time-reversal operator. The analysis uses a sample of proton-proton co...
