twoLeptonGen A Monte Carlo event generator for the process , with or , when both the proton target and the antiproton beam are unpolarized, is described. The input cross section is a leading order calculation with a massive lepton in the final state. The generator is a useful first tool to study lepton production at PANDA. The generator is part of the current "trunk" version of PANDA ROOT. Full documentation for the event generator can be found here

A Monte Carlo event generator for the process ,
when both the proton target and the antiproton beam are unpolarized, is described.
The kinematic region covers the antiproton momentum range
from 0.79GeV to 12.0GeV, in the LAB frame.
For the low energy regime, the parametrization of the cross section
is based on a Legendre polynomial fit to data from the (antiproton beam)
CERN 28GeV proton synchroton.
For the high energy regime, the recent predictions by J. van de Wiele and S. Ong
based on a Regge Theory approach were used.
The generator is a useful first tool to study pion production at PANDA.
The generator is part of the current "trunk" version of PANDA ROOT.
Full documentation for the event generator can be found here.
The and cross section We describe the differential cross section for the processes , with or , and , when both the proton target and the antiproton beam and the antiproton beam are unpolarized. For lepton production, the cross section is a leading order calculation with a massive lepton in the final state. For pion production, the parametrization of the cross section in the low energy regime is based on a Legendre polynomial fit to data from the (antiproton beam) CERN 28GeV proton synchroton, whereas in the high energy regime the recent predictions by J. van de Wiele and S. Ong based on a Regge Theory approach were used. A computer code to perform integration of both the lepton and pion cross section in a userdefined kinematic region is also described. Full documentation can be found here. A tar (gziped) file with the computer code to perform numerical integration of both the lepton and pion cross section can be found here.
