Use of input beam energy distribution for photon-heavy nucleus collision
Hello,
I am trying to simulate a photon - lead nucleus collision using MadGraph UFO model. This is the command I use:
generate a nuc > ax nuc
where nuc is the lead nucleus (having adequate form factor defined in my model), ax is an Axion Like Particle (defined in my UFO model). This generation is successful when I provide specific energies to the input beams:
set run_card ebeam1 2.2
set ebeam2 0.
for incoming photon energy of 2.2 GeV and lead nucleus at rest.
But in a realistic experiment, the incoming photon beam will not have exactly 2.2 GeV of energy - there will be a distribution of incoming photon beam energy. In a proton-proton collision, this is handled by the PDF provided. But for this photon-nucleus collision scenario, how I can inform MadGraph that the incoming photon beam energy is not constant? We have a text file of the incoming photon beam energy distribution (kind of a lookup table). Is there a nice way to tell MadGraph to use that photon energy distribution?
Thank you,
Arka
