ColoRea: Colour Rearrangement for Dipole Showers

Abstract

In this talk I presented an algorithm to correct for wrong assignment of colour dipoles in the cascade of dipole showers. It is explained how simple matrix elements can be used to reorder the colour connections for the evolution of the following cascade. I discuss the possibility to modify the splitting kernels to include an improved behaviour. Further a numerical study is presented that indicates the insensitivity of reordering with matrix elements of higher multiplicity
