Description
In this talk, I will discuss the recent calculation of open bottom production at hadron colliders at next-to-next-to-leading order including the resummation of quasi-collinear logarithms through next-to-next-to-leading-logarithmic accuracy. This computation essentially extends the FONLL approach from NLO+NLL to NNLO+NNLL in a straightforward way, allowing for the computation of fully differential observables involving $b$-quarks, $B$-hadrons or $B$-hadron decay products. Aside from the technical details, I will also discuss comparisons to data, where the significantly improved predictions highlight a discrepancy in non-prompt $J/\psi$ production.
