electron photon collision

Asked by Stuti Parashar

Hello,

I was trying to generate the events for the linear collider using the electron photon collision.
The photon is not coming from the positron rather a photon from the LASER beam which gives the process as

generate e- a > x y

for the linear collider set up of the MadGraph.

In a recent MadGraph version (2.6.4), at the time of setting the PDF I do not find this option.
I found that there is an option for photons radiated from electron, however, that will not work for this process.

How to implement this process in MadGraph for event generation?

Many Thanks,
Stuti

Hi,

This option is technically implemented (by me):
https://bazaar.launchpad.net/~maddevelopers/mg5amcnlo/laser_beam_option/revision/246 <https://bazaar.launchpad.net/~maddevelopers/mg5amcnlo/laser_beam_option/revision/246>
but was never released because no one was ever interested to validate it.
If you want you can use the above branch/tarball to do that.

If you are doing such validations, we can write a small paper describing such new features/validations.
And in that case, I can start by updating that branch with the latest version of the code.

Cheers,

Olivier
