Parity violating asymmetries in top quark pair production at hadron colliders
Parity violating asymmetries in top quark pair production at hadron colliders
We study loop-induced parity violating asymmetries in the strong production of polarized top quark pairs at $\mathrm{pp}$ and $p\overline{p}$ colliders. The electroweak $\mathcal{O}(\ensuremath{\alpha})$ corrections to the helicity amplitudes of $q\overline{q}\ensuremath{\rightarrow}t\overline{t}$ and $g\stackrel{\ensuremath{\rightarrow}}{g}t\overline{t}$ are evaluated in a two Higgs doublet model (2HDM) and the minimal supersymmetric standard model (MSSM).
