Abstract The GR@PPA event generator has been updated to version 2.7. This distribution provides event generators for V (W or Z)+jets (⩽4 jets), V V + jets (⩽2 jets) and QCD multi-jet (⩽4 jets) production processes at pp and p p ¯ collisions, in addition to the four bottom quark productions implemented in our previous work (GR@PPA_4b). Also included are the top-pair and top-pair+jet production processes, where the correlation between the decay products are fully reproduced at the tree level. N... Title of program: GR@PPA (v2.7) Catalogue Id: ADRH_v2_0 Nature of problem The multi-legs interaction processes have become more important with increasing the colliding energy available at the high energy collider experiments. At hadron-collider experiments, since thousands of Feynman diagrams contributes in the single ineraction process, the faster and more stable calculation to obtain the results is desirable.
