Momentum distributiin

Asked by Ekaterina on 2019-12-09

Hello dear CalcHEP experts!

I need to do some dependings of diff cross-section on 3-momentum of outgoing particle.

For example, our process looks like X -> e+ e+ gamma. Can we in some way get this distributions (for example on e+ momentum)?

If i understand it correctly, distributions on transverse momentum isnt suitable for this task?

Thank you

There is built-in  E function which allows to get distribution over
energy of  particle.

If it enough for you? If not there is a possibility to add user
function. But one has to write a C-code for it.

   Let us know if you need our  help for realization of user function.
