Description
We present new high precision predictions for bottom-quark pair production in hadronic collisions. These results are obtained through the implementation of a Monte Carlo event generator in the Powheg-Box framework, where the MiNNLOps method has been applied to match the next-to-next-to-leading order (NNLO) calculation to parton showers. Distributions inclusive over QCD radiation are NNLO accurate, while distributions for bottom-quark pair production in association with one final-state hard jet are next-to-leading order accurate. We validate our results against a fixed-order NNLO calculation and present a first comparison of NNLO+PS predictions with experimental data from the LHC.
