| Abstract: | A scheme for including the first-order matrix element in ep parton showers is presented. This is an important improvement since it applies to hard emission where the leading-log approximation is less reliable. The contributions from the initial-and final-state showers are treated on an equal footing, solving the potential problem of double-counting of emission. Kinematical constraints, relating the dynamics of the two separate showers, are also solved in this context. The choice of splitting variable in initial-state showers is furthermore discussed. |
