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.

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.
