Member Function Documentation

◆ getMass()

virtual Energy Herwig::WidthCalculatorBase::getMass ( const int  imass) const
pure virtual

Get the mass of one of the decay products.

This must be implemented in classes inheriting from this one.

Parameters
imassThe mass required.
Returns
The mass required.

Implemented in Herwig::ThreeBodyAllOnCalculator< T >, Herwig::OneOffShellCalculator, Herwig::TwoOffShellCalculator, Herwig::ThreeBodyAllOn1IntegralCalculator< T >, and Herwig::TwoBodyAllOnCalculator.

◆ otherMass()

virtual Energy Herwig::WidthCalculatorBase::otherMass ( const int  imass) const
pure virtual

Get the masses of all bar the one specified.

Used to get the limits for integration.

Parameters
imassThe particle not needed
Returns
The sum of the other masses.

Implemented in Herwig::ThreeBodyAllOnCalculator< T >, Herwig::TwoBodyAllOnCalculator, Herwig::OneOffShellCalculator, Herwig::ThreeBodyAllOn1IntegralCalculator< T >, and Herwig::TwoOffShellCalculator.

◆ partialWidth()

virtual Energy Herwig::WidthCalculatorBase::partialWidth ( Energy2  scale) const
pure virtual

Calculate the partial width.

This must be implemented in classes inheriting from this one.

Parameters
scaleThe mass squared of the decaying particle.
Returns
The partial width.

Implemented in Herwig::ThreeBodyAllOnCalculator< T >, Herwig::OneOffShellCalculator, Herwig::TwoOffShellCalculator, Herwig::ThreeBodyAllOn1IntegralCalculator< T >, and Herwig::TwoBodyAllOnCalculator.

◆ resetMass()

virtual void Herwig::WidthCalculatorBase::resetMass ( int  imass,
Energy  mass 
)
pure virtual

Reset the mass of a particle (used to integrate over the mass.) This must be implemented in classes inheriting from this one.

Parameters
imassThe mass to be reset.
massThe new mass.

Implemented in Herwig::ThreeBodyAllOnCalculator< T >, Herwig::OneOffShellCalculator, Herwig::TwoOffShellCalculator, Herwig::ThreeBodyAllOn1IntegralCalculator< T >, and Herwig::TwoBodyAllOnCalculator.
