ActionFinderInterface is the abstract base class for all action finders, i.e.
A simple decay finder: Just loops through all particles and checks if they can decay during the next ...
ActionList find_actions_with_surrounding_particles(const ParticleList &, const Particles &, double, const std::vector< FourVector > &) const override
Ignore the surrounding searches for decays.
DecayActionsFinder(double res_lifetime_factor)
Initialize the finder.
const double res_lifetime_factor_
Multiplicative factor to be applied to resonance lifetimes.
ActionList find_final_actions(const Particles &search_list, bool only_res=false) const override
Force all resonances to decay at the end of the simulation.
ActionList find_actions_in_cell(const ParticleList &search_list, double dt, const double, const std::vector< FourVector > &) const override
Check the whole particle list for decays.
ActionList find_actions_with_neighbors(const ParticleList &, const ParticleList &, double, const std::vector< FourVector > &) const override
Ignore the neighbor searches for decays.
The Particles class abstracts the storage and manipulation of particles.
