It generates $pp\toη_b X$ events for all possible parton-level $2\to2$ leading-order processes with three commonly used $η_b$ decay channels being implemented. The \pythia interface is used for parton-shower and hadronization to obtain the hadronic events. The FORTRAN codes of this package are generated by FDC (Feynman Diagram Calculation) system automatically.23 pages, 6 figuresHigh Energy Physics - PhenomenologyHigh Energy Physics - ExperimentEtabFDC: an $η_b$ event generator in hadroproduction at LHCtext
