GenEv

Inelastic Electron Event Generator

Introduction

GenEv is the Inelastic electron event generator of Genova Group.  Here is a short overlook.
The electron extraction can be made in 4 different way:
- fixing an interval of omega and theta (Q2 and W free)
- fixing an interval omega and theta  and Q2 (W free)
- fixing an interval of omega and theta  and W (Q2 free)
- fixing an interval of Q2 and W  (omega and theta free)
setting some lags in the input file.
Q2 distribution is the same for all channels. GENEV can be used up to W~3.5 GeV but it was tested up to W~ 2.5-3.0 GeV
(at high W it's necessary  to include other channels).
The hadrons are extracted according to the existing data (interpolated when necessary) or acoording to some phenomenological model.
Theta distribution are generally realistic while phi distribution is uniform but for 1 pion (a+bcosphi+c cos2phi).
Theta distribution for omega and phi are the same of the rho.
Decay distributions are always uniform but for rho where phi and theta come from a phenomenological model.
