Measurement of tt̄ Helicity Fractions and Spin Correlation Using Reconstructed Lepton + Jets Events

  • Published 2010

Abstract

Standard model top pair production produces a characteristic spin correlation which can be modified by new production mechanisms such as Z ′ bosons or Kaluza-Klein gluons. In the standard model, top quarks decay weakly before any hadronization processes take effect, enabling top spin information to be transmitted to the top quark decay products. We report… (More)
