NNLO+PS predictions for Higgs production through bottom-quark annihilation with MINNLO$$\varvec{_{\text {PS}}}$$

Abstract

AbstractWe consider Higgs production through bottom-quark annihilation at hadron colliders and we calculate next-to-next-to-leading-order (NNLO) corrections in QCD perturbation theory matched to parton showers (NNLO+PS). To this end, we have adapted the MINNLO$$\varvec{_{\text {PS}}}$$ PS method to account for the extra scale dependence induced by an overall Yukawa coupling that is $$\overline{\textrm{MS}}$$ MS ¯ renormalized. We compare our results against state-of-the-art fixed-order predictions at NNLO as well as resummed predictions at next-to-next-to-leading-logarithmic (NNLL) accuracy.
