Pair production of scalar leptoquarks at the Tevatron

Abstract

We present the cross section for pair production of scalar leptoquarks $LQ$ in $p\bar{p}$ collisions, $p+\bar{p} \to LQ + \bar{LQ} + X$, at the Fermilab Tevatron in next-to-leading order QCD. Including the higher-order corrections stabilizes the theoretical prediction and increases the size of the cross section for renormalization/factorization scales close to the mass of the leptoquarks. This leads to an increase of the lower bound on the mass of scalar leptoquarks by up to 15 GeV with respect to earlier analyses.
