The LHCEW group on Jets and EW bosons proposes to produce an LHC tune
to provide consistent parameters for the different parton shower and MPI
MC generators. The LHC tune will include data from all LHC collaborations, as well as lower energy data. The parameters to be tuned are those of the UE event and intrinsic kt, but are not connected with the hard process.
The goal is to provide a tune which can be used with any of the higher order
calculations to provide consistent predictions.
