particle [@Bahr:2008pv] and therefore the dipole describing the singular behaviour of this particle will only contain a universal soft contribution. This is a well defined, spin-independent function given, for the example colour flow $3 \rightarrow 3\,0$, by Eq. \[eq:initialDipole\].

Finally, in this work we focus solely on the effect of the POWHEG correction on the simulation of the hardest emission in the shower and have not implemented the normalisation factor coming from the presence of $\bar{B}$ rather than $B$ in Eq. \[eq:PO\]. In many cases, the partial widths and branching ratios used in the simulation are calculated by an external program, for example SDECAY [@Muhlleitner:2003vg], and so already include NLO corrections. These values are then passed to  by means of a spectrum file in SUSY Les Houches Accord format [@Allanach:2004ub; @Allanach:2008qq]. In cases where the calculation of the widths and branching ratios is performed in , generated distributions can be rescaled by a global normalisation factor to achieve NLO accuracy for suitably inclusive observables when the necessary calculations exist.
