A module to simulate nucleon decays.
description

This module is converted from the GENIE nucleon decay event generation application: ${GENIE}/src/support/ndcy/EvGen/gNucleonDecayEvGen.cxx. It supports 11 nucleon decay nodes:

———————————————————
ID |   Decay Mode                     |   Current Limit
|                                  |   (1E+34 yrs)
———————————————————
0 |   p –> e^{+}      + \pi^{0}     |   1.3
1 |   p –> \mu^{+}    + \pi^{0}     |   1.1
2 |   p –> e^{+}      + \eta^{0}    |   0.42
3 |   p –> \mu^{+}    + \eta^{0}    |   0.13
4 |   p –> e^{+}      + \rho^{0}    |   0.07
5 |   p –> \mu^{+}    + \rho^{0}    |   0.02
6 |   p –> e^{+}      + \omega^{0}  |   0.03
7 |   p –> \mu^{+}    + \omega^{0}  |   0.08
8 |   n –> e^{+}      + \pi^{-}     |   0.2
9 |   n –> \mu^{+}    + \pi^{-}     |   0.1
10 |   p –> \bar{\nu}} + K^{+}       |   0.4

The FHiCL parameter DecayMode is used in selecting decay mode. Currently this module only simulates nucleon decay in Ar nucleus. It calls functions in GENIE to do simulation and converts the GENIE record to MCTruth. It distributes decay position randomly inside TPC active volume. The output file can be passed to the next standard g4 simulation.
