Answer 2

Explanation:

• In the Madgraph language, it is a multiparticle, which means it contains as partons the gluon (g) and light quarks (u, d, s, c) and light antiquarks (u~, d~, s~, c~). Madgraph automatically sums over all of these with the appropriate parton distribution function (PDF) weights. It uses the CTEQ6L1 set of PDFs.
