◆ change()

static void Herwig::DipolePartonSplitter::change ( tPPtr  parent,
tPPtr  child,
bool  initialState,
bool  decayedSpec = false 
)
static

Fix up relations for the case that the new parton instance exists only due to changes in e.g.

kinematics.

◆ split() [1/2]

static void Herwig::DipolePartonSplitter::split ( tPPtr  parent,
tPPtr  firstChild,
tPPtr  secondChild,
bool  initialState,
bool  decayedEmitter = false 
)
static

Fix up mother child relations for splitting the first to the second and third parton; use conventions of a backward splitting, if initialState is true.

In this case, the first child is assumed to be the new incoming parton.

◆ split() [2/2]

static void Herwig::DipolePartonSplitter::split ( tPPtr  parent,
tPPtr  firstChild,
tPPtr  secondChild,
tPPtr  ref,
bool  initialState,
bool  decayedEmitter = false 
)
static

Fix up relations for splitting the first to the second and third parton; use conventions of a backward splitting, if initialState is true.

In this case, the first child is assumed to be the new incoming parton. A reference is given to determine which colour line did actually radiate in case of ambiguities, in the sense that the colour connected parent-ref pair raidated as a dipole.
