Measurement of the Mass Difference Between Top Quark and Antiquark in pp Collisions At √s=8 TeV

The invariance of the standard model (SM) under the CPT transformation predicts equality of particle and antiparticle masses. This prediction is tested by measuring the mass difference between the top quark and antiquark (Δmt=mt−mt‾) that are produced in pp collisions at a center-of-mass energy of 8...
