Merging Corner:

Another sample main program for merging in Pythia8. This example includes another way of using a user-defined merging scale. The program can e.g. be used with the input main86.cmnd.

Merging in Pythia8: User tutorial

A tutorial how to use CKKW-L merging in Pythia8. The tutorial was originally written for the Helmholtz Alliance Monte Carlo School 2012 at DESY, Hamburg. Most references to this school have been removed for the sake of portability. Please excuse any references to any school-specific setup in the tutorial.
