Supersymmetric QCD one-loop effects in (un)polarized top-pair production at hadron colliders
We study the effects of $\mathcal{O}({\ensuremath{\alpha}}_{s})$ supersymmetric QCD (SQCD) corrections on the total production rate and kinematic distributions of polarized and unpolarized top-pair production in $pp$ and $p\overline{p}$ collisions. At the Fermilab Tevatron $p\overline{p}$ collider, top-quark pairs are mainly produced via quark-antiquark annihilation, $q\overline{q}\ensuremath{\rightarrow}t\overline{t}$, while at the CERN LHC $pp$ …
