Member Function Documentation

void decayOne ( TauolaParticle *  tau,
bool  undecay = false,
double  polx = 0,
double  poly = 0,
double  polz = 0 
) [static]

Tau gun. Takes one particle that's already inside an event record and produces it's decay. The tau provided may be undecayed first, or left intact if it already has daughters. If the polarization three-vector is provided it will be used to construct m_R matrix.

Definition at line 506 of file Tauola.cxx.

void decayOneBoost ( TauolaParticle *  mother,
TauolaParticle *  target 
) [static]

Execute boost routine for decayOne()

Definition at line 572 of file Tauola.cxx.
