To implement matching of fixed order matrix elements to the dipole cascade in Ariadne both for W production in hadron collisions and for DIS. The method used is based on the CKKW prescription modified with PS-generated Sudakovs and 'inverse cascade' instead analytical Sudakovs and kt-jetfinding, as has already been implemented in Ariadne for e⁺e^-.

None at the moment. Maybe an experimental collaborator could help at a later stage when more extensive comparison to data is called for

Preliminary results was presented at the working group meeting at DESY in the beginning of June.

(2004.10.15) The matching has been implemented both for W-production and DIS. Detailed investigation on the performance of the matching is almost finished for W-production.
