GR@PPA_4b: A four bottom quark production event generator for pp/p p ̄ collisions

Abstract
We have developed an event generator, named GR@PPA_4b, for the four bottom quark (b b ̄ b b ̄ ) production processes at pp and p p ̄ collisions. The program implements all of the possible processes at the tree level within the framework of the Standard Model. Users can g...

Title of program: GR@PPA_4b (v1.0)
Catalogue Id: ADRH_v1_0

Nature of problem
Four bottom-quark production is an important channel for the study of Higgs-boson properties at future high energy hadron-collider experiments. However, the detectability is very ambiguous because only crude estimates based on many approximations have been available for background processes.
