The most common is [[pair production|production of a top–antitop pair]] via [[strong interaction]]s. In a collision, a highly energetic [[gluon]] is created, which subsequently decays into a top and antitop. This process was responsible for the majority of the top events at Tevatron and was the process observed when the top was first discovered in 1995.<ref name=D0-2009/> It is also possible to produce pairs of top–antitop through the decay of an intermediate [[photon]] or [[Z-boson]]. However, these processes are predicted to be much rarer and have a virtually identical experimental signature in a [[hadron collider]] like Tevatron.
