Detailed Description

The ColourLines class defines the colour flow in a SubProcess.

It defines a number of colour lines and specifies which particles are connected to them.

Constructor & Destructor Documentation

◆ ColourLines()

ThePEG::ColourLines::ColourLines ( string  s)

The standard constructor.

The string s should contain a comma-separated sequence of integers. Each sequence of numbers indicates a colour line and the integer represents a parton connected to it. If the integer is negative, it means that the line is the corresponding partons anti-colour. Note that the partons are numbered from 1: The first spacelike particle is 1, the second is 2 and the internal time-like and outgoing are numbered after all the spacelike particles.

Member Function Documentation

◆ connect()

void ThePEG::ColourLines::connect ( const tPVector partons) const

Create the corresponding ColourLines and connect the given partons.

The partons are assumed to be in the same order as the numbers specified in the constructor.

Referenced by ColourLines().

◆ reset()

void ThePEG::ColourLines::reset ( string  s)

Reset this ColourLines object.

The string s should contain a comma-separated sequence of integers. Each sequence of numbers indicates a colour line and the integer represents a parton connected to it. If the integer is negative, it means that the line is the corresponding partons anti-colour. Note that the partons are numbered from 1: The first incoming is 1, the second is 2 and the internal and outgoing are numbered 3 and upwards.
