Measurement of the top - antitop mass difference in pp collisions at sqrt(s) = 8 TeV
The invariance of the standard model under the CPT transformation predicts equality of particle and antiparticle masses. This prediction is tested by measuring the mass difference between the top and the antitop quark ($\Delta m_{\text{t}} = m_{\mathrm{t}} - m_{\overline{\mathrm{t}}}$), using events...
