B-hadron production at the LHC from bottom-quark pair production at NNLO+PS

The production of B hadrons is among the most abundant fundamental QCD processes measured at LHC. We present for first time predictions this process accurate to next-to-next-to-leading order in perturbation theory by simulating bottom-quark pair accuracy matched parton showers. Our novel results are good agreement with experimental data different types from ATLAS, CMS and LHCb 7 TeV and/or 13 TeV, including various fiducial cross sections as well single- double-differential distributions, TeV/7 cross-section ratios.
