B-hadron fragmentation at NNLO in QCD
In the paper arXiv:2210.06078 (by Czakon, Generet, Mitov and Poncelet) the following sets of NNLO b-fragmentation functions were produced:
- B-hadron production
- J/ψ production ( J/ψ originating in hadronic B decays)
- muon production (μ originating in semileptonic B->μ+X decays)
Each set consists of 100 members which allows for detailed fragmentation function uncertainty estimates (see the above reference for details).
We thank Gennaro Corcella for a collaboration at an early stage of this work and for numerous useful comments and suggestions.
