  // Geant4 does not define the decay of most of charmed and bottom hadrons.
  // The reason is that most of these heavy hadrons have many different
  // decay channels, with a complex dynamics, quite different from the flat
  // phase space kinematical treatment used in Geant4 for most of hadronic decays.
  // High-energy experiments usually use dedicated Monte Carlo Event Generators
  // for the decays of charmed and bottom hadrons; therefore, these heavy
  // hadrons, which are passed to Geant4 as primary tracks, have pre-assigned
  // decays. Moreover, no charmed or bottom secondary hadrons were created
  // in Geant4 hadronic interactions before Geant4 10.7.
  // With the extension of Geant4 hadronic interactions to charmed and bottom
  // hadrons, in version Geant4 10.7, we do need to define decays in Geant4
  // for these heavy hadrons, for two reasons:
  // 1. For testing purposes, unless we pre-assign decays of heavy hadrons
  //    (as the HEP experiments normally do by using MC Event Generators);
  // 2. To avoid crashes (due to missing decay channels) whenever charmed or
  //    bottom secondary hadrons are produced by Geant4 hadronic interactions,
  //    even with ordinary (i.e. not heavy) hadron projectiles, because in
  //    this case we cannot (easily!) pre-assign decays to them.
  // Given that 1. is just a convenience for testing, and 2. happens rather
  // rarely in practice - because very few primary energetic (i.e. boosted)
  // heavy hadrons fly enough to reach the beam pipe or the tracker and
  // having an inelastic interaction there, and the very low probability
  // to create a heavy hadrons from the string fragmentation in ordinary
  // (i.e. not heavy) hadronic interactions - there is no need in practice
  // to define accurately the decays of heavy hadrons in Geant4.
  // So, for our practical purposes, it is enough to define very simple,
  // "dummy" decays of charmed and bottom hadrons.
  // Here we use a single, fully hadronic channel, with 2 or 3 or 4
  // daughters, for each of these heavy hadrons, assigning to this single
  // decay channel a 100% branching ratio, although in reality such a
  // channel is one between hundreds of possible ones (and therefore its
  // real branching ratio is typical of a few per-cent); moreover, we treat
  // the decay without any dynamics, i.e. with a flat phase space kinematical
  // treatment.
  // Note that some of the charmed and bottom hadrons such as SigmaC++,
  // SigmaC+, SigmaC0, SigmaB+, SigmaB0 and SigmaB- have one dominant
  // decay channel (to LambdaC/B + Pion) which is already defined in Geant4.
  // This is not the case for EtaC, JPsi and Upsilon, whose decays need to
  // be defined here (although they decay so quickly that their hadronic
  // interactions can be neglected, as we do for Pi0 and Sigma0).
  // Note that our definition of the decay tables for these heavy hadrons
  // do not interfere with the pre-assign decays of primary charmed and
  // bottom tracks made by the HEP experiments. In fact, pre-assign decays
  // have priority over (i.e. override) decay tables.
