Detailed Description

The HwRemDecayer class is responsible for the decay of the remnants.

Additional secondary scatters have to be evolved backwards to a gluon, the first/hard interaction has to be evolved back to a valence quark. This is all generated inside this class, which main methods are then called by the ShowerHandler.

A simple forced splitting algorithm is used. This takes the Remnant object produced from the PDF and backward evolution (hadron - parton) and produce partons with the remaining flavours and with the correct colour connections.

The algorithim operates by starting with the parton which enters the hard process. If this is from the sea there is a forced branching to produce the antiparticle from a gluon branching. If the parton entering the hard process was a gluon, or a gluon was produced from the first step of the algorithm, there is then a further branching back to a valence parton. After these partons have been produced a quark or diquark is produced to give the remaining valence content of the incoming hadron.

The forced branching are generated using a scale between QSpac and EmissionRange times the minimum scale. The energy fractions are then distributed using

\[\frac{\alpha_S}{2\pi}\frac{P(z)}{z}f(x/z,\tilde{q})\]

with the massless splitting functions.
