Dear colleagues,
I contact you to ask if, in FLUKA, the charge-exchange reaction initiated by a 40 GeV pi- beam impinging on a heavy nuclei, resulting to the production of a neutral pseudo-scalar meson, is included in the list of processes that are simulated:
\pi^- p \rightarrow \eta (\eta^\prime) n
where p is a proton inside the nuclei and n is the recoiling neutron, taking almost no energy (the reaction is strongly peaked at very low |t|).
Thanks,
Bests,
Andrea
