Parameters
osThe stream to output the information to
headerWhether or not to output the information for MySQL

Implements Herwig::HwDecayerBase.

Reimplemented in Herwig::WeakPartonicDecayer, Herwig::QuarkoniumDecayer, Herwig::HeavyDecayer, and Herwig::BtoSGammaDecayer.

◆ decay() [1/2]

virtual ParticleVector Herwig::PartonicDecayerBase::decay ( const Particle parent,
const tPDVector children 
) const
pure virtual

Perform the decay of the particle to the specified decay products.

Parameters

const Particle p 
) const
virtual

Perform a decay for a given DecayMode and a given Particle instance.

Parameters
dmthe DecayMode describing the decay.
pthe Particle instance to be decayed.
Returns
a ParticleVector containing the decay products.

Reimplemented from Herwig::HwDecayerBase.

◆ duplicateMode()

bool Herwig::PartonicDecayerBase::duplicateMode ( const Particle parent,
const vector< tPPtr > &  hadrons

hadronsThe hadrons produced in the partonic decay.
Returns
Whether or not there are duplicate modes.

◆ Init()

static void Herwig::PartonicDecayerBase::Init ( )
static

The standard Init function used to initialize the interfaces.

Called exactly once for each class by the class description system before the main function starts or when this class is dynamically loaded.

◆ operator=()

PartonicDecayerBase& Herwig::PartonicDecayerBase::operator= ( const PartonicDecayerBase )
privatedelete

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

void Herwig::PartonicDecayerBase::persistentInput ( PersistentIStream is,
int  version 
)

Function used to read in object persistently.

Parameters
isthe persistent input stream read from.
versionthe version number of the object when written.
