NNLO+PS predictions for Higgs production via bottom annihilation

Abstract

We report on the implementation of a new NNLO+PS event generator for the Higgs production via bottom annihilation using the MiNNLOPS method in the POWHEG framework. The calculation has been carried out in the five flavour scheme (5FS), where the bottom mass is neglected. We compare our results against fixed-order predictions at NNLO as well as resummed predictions at next-to-next-to-leading-logarithmic (NNLL) accuracy. We also present a preliminary study in the four flavour scheme (4FS) setup, achieving a new level of precision in the massive scheme.
