EtabFDC: an $\eta_b$ event generator in hadroproduction at LHC

Abstract

The EtabFDC is a matrix-element event generator package for $\eta_b$ hadroproduction at LHC. It generates $pp\to\eta_b X$ events for all possible parton-level $2\to2$ leading-order processes with three commonly used $\eta_b$ 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.
