P-wave contribution to third-order top-quark pair production near threshold

Abstract

The next-to-leading order (NLO) P-wave Coulomb Green function contributes at third-order to top-pair production in e+ e- collisions near threshold. In this paper we compute the NLO P-wave Green function in dimensional regularization, as required for a consistent combination with non-resonant production of the W+ W- b\bar{b} final state, and present a phenomenological analysis of the P-wave contribution. We further briefly discuss squark production near threshold and top-pair production in gamma gamma collisions, where no S-wave contribution is present, and the P-wave thus constitutes the dominant production process.
