/eN_eventDefinition [ Modules ]
NAME
module eN_eventDefinition
PURPOSE
This module includes a type definition which deals with kinematics of lepton-nucleon scattering.
NOTES
- historically, this type was developed to hold informations in electron induced reactions. Since we enhanced the usage also to neutrino induced reactions, it should be renamed into "type leptonNucleon_event".

NAME
type electronNucleon_event
PURPOSE
This is a type to define an electron-nucleon scattering event
SOURCE
Type electronNucleon_event
type(particle) :: lepton_in ! incoming lepton (or neutrino)
type(particle) :: lepton_out ! outgoing lepton
type(particle) :: boson ! exchanged boson
type(particle) :: nucleon ! target nucleon
type(particle) :: nucleon_free ! free target nucleon (potentials removed)
type(particle) :: nucleon2 ! second target nucleon (2p2h processes)
real :: Q2 = 0. ! Q^2=-q^2
real :: W = 0. ! W at the hadronic vertex
real :: W_free = 0. ! Free W (potentials removed, momentum kept)
real :: W_rec = 0. ! Free W for nucleon at rest
real, dimension(0:3) :: pcm = 0. ! Lorentz-Trafo into cm-frame
real, dimension(3) :: betacm = 0. ! Lorentz-Trafo into cm-frame
real :: phiLepton = 0.! additional angle of lepton plane
integer :: idProcess = 0 ! = (+-)EM,(+-)CC,(+-)NC
integer :: idFamily = 0 ! Abbrev. for: e,mu,tau
end Type electronNucleon_event
NOTES
1) The integers 'idProcess' and 'idFamily' keep redundant information, but are useful as abbreviations in if-statements. (cf.module leptonicID)
