Equivalent Photon Approximation (EPA) fluxes

Asked by Patricia Rebello Teles

Dear authors,

I intend to deal with Equivalent Photon Approximation (EPA) fluxes for colliding e+ e-
I know that Madgraph has EPA implemented for both, from eletrons and protons.

so, in the case I want to play with e+ e- > gamma gamma channel, should I just use PDF=3 and play with q2max Photon Flux accordingly?

Thank you.

CHeers Patricia
