Editing Top quark (section)

== Properties ==
* At the final Tevatron energy of 1.96&nbsp;TeV, top–antitop pairs were produced with a [[Cross section (physics)|cross section]] of about 7&nbsp;[[picobarn]] (pb).<ref name=D0-CDF/> The [[Standard Model]] prediction (at [[leading-order#Next-to-leading order|next-to-leading order]] with {{math|size=120%|''m''}}{{sub|t}} = {{val|175|u=GeV/c2}}) is 6.7–7.5&nbsp;[[picobarn|pb]].
* The W bosons from top quark decays carry polarization from the parent particle, hence pose themselves as a unique probe to top polarization.
* In the Standard Model, the top quark is predicted to have a spin quantum number of {{sfrac| 1 |2}}&nbsp;''e'' and electric charge {{sfrac|+| 2 |3}}&nbsp;''e''. A first measurement of the top quark charge has been published, resulting in some confidence that the top quark charge is indeed&nbsp;{{sfrac|+| 2 |3}}&nbsp;''e''.<ref name=Abazov2007a/>
