void compute(ParticlePropagator &Particle, RandomEngineAndDistribution const *) override
Generate Bremsstrahlung photons.
unsigned int poisson(double ymu, RandomEngineAndDistribution const *)
Generate numbers according to a Poisson distribution of mean ymu.
BremsstrahlungSimulator(double photonEnergyCut, double photonFractECut)
Constructor.
double gbteth(const double ener, const double partm, const double efrac, RandomEngineAndDistribution const *) const
A universal angular distribution - still from GEANT.
~BremsstrahlungSimulator() override
Default destructor.
double xmin
The fractional photon energy cut (determined from the above two)
double photonEnergy
The minimum photon energy to be radiated, in GeV.
XYZTLorentzVector brem(ParticlePropagator &p, RandomEngineAndDistribution const *) const
Compute Brem photon energy and angles, if any.
double photonFractE
