The parton level analysis is running on b-loop produced gg->bbA events for two generation setups: with bb pair from gluon splitting by PY8 shower with with full LO ME b-loop produced gg->bbA. The full LE ME events are produced by Olivier Mattelaer with MG5_aMC@NLO. For 1st approach, g->bb from shower the NLO generators POWHEG and MG5_aMC@NLO are used with PY8 showering. | + | bbA.
