Pseudo-scalar Higgs production at next-to-leading order SUSY-QCD

Abstract

The production rate of the CP-odd Higgs boson in the Minimal Supersymmetric Standard Model is evaluated through next-to-leading order in the strong coupling constant. The divergent integrals are regulated using Dimensional Reduction, with a straightforward implementation of ${\gamma }_5$. The result is confirmed within Dimensional Regularization where ${\gamma }_5$ is implemented according to the Standard Model calculation of Chetyrkin et al. The well-known Standard Model result is recovered if the masses of the supersymmetric particles tend to infinity.
