SCENARIO A2

In this model the axigluon decays to color octet scalars, which we called pions in the UFO implementation. In this implementation the scalars decay to a uubar pair. This is an alternative version of Scenario A described in <1209.6375> given that currently MadGraph 5 crashes with 8 gluons in the final state.

PARAMETERS:
(all the parameters are explicitly defined in our paper 1209.6375)

gaxi: coupling of the axigluon to the light quarks, corresponds to $g_A$ in our paper. The couplings to heavy quarks are all determined once this is fixed by the relations described in appendix A in our paper. This is also true for the coupling of heavy quarks to the pion.

lpion: coupling of the pion to u ubar.

HOW TO GENERATE THE FULL DECAY CHAIN

generate p p > axi axi, ( axi > pion pion, pion >u u~ )
