oneBodyDecay/oneBodyVADecay

oneBodyDecay / oneBodyVADecay:

Works with VSimPD license.

Kinds of MonteCarlo interactions that model the decay of an unstable particle into a single final-state particle.

oneBodyVADecay choses the energy and momentum of the final-state particle is based on the V-A theory. This is valid, for example, for describing the decay of muons into electrons, where the final-state neutrinos are not kinetically modeled. The momentum of the final-state particle however takes into account that part of the momentum of the unstable particle is carried away by one or several neutrinos.

Note

This feature replaces the oneBodyVADecay and oneBodyVADecayVW features previously implemented in Vorpal collisions.

oneBodyDecay/oneBodyVADecay Parameters

unstableSpecies (string)

This specifies the name of the unstable (decaying) species.

lifetime (real)

This specifies the unstable species lifetime in seconds.

productSpecies (string)

This specifies the Species product of the decay of the unstable species.

isDissociation (boolean)

If true, the unstable species decays into two resultant productSpecies particles.

Example oneBodyDecay Block

<Interaction Decay>
  kind = oneBodyDecay
  unstableSpecies = muons
  productSpecies = electrons
  lifetime = 2.2e-6
<Interaction>
