If you are interested in doing a Merging run, you can use the file LHC-W-Merging.in file, but this will take a long time for the integration step. For the sake of making more runs with more stats better use the LHC-W-Matching.in input file

For using the Rivet analysis: copy the MY_W_ANALYSIS.cc, MY_W_ANALYSIS.plot and MY_W_ANALYSIS.yoda.gz to the herwig directory and type make RivetMY_W_ANALYSIS.so to compile the analysis

For changing the W boson mass there is a snippet called MassW.in where you can change the value for the W+ and W- boson individually, so remember to change both masses to the same value to be consistent.

Run assignments:

send the yoda files with the convention "LHC-W-80_XXXXXXX.yoda" to stefan.kiebacher@kit.edu

For parallelising the run steps :

DRH Herwig run LHC-W-Matching.run --jobs=N_CORES -N N_EVENTS
DRH rivet-merge -e LHC-W-Matching-*.yoda -o  LHC-W-Matching.yoda

For not doing the read step again do:

DRH Herwig run LHC-W-Matching.run --jobs=N_CORES -N N_EVENTS --setup=MassW.in
DRH rivet-merge -e LHC-W-Matching-*.yoda -o  LHC-W-Matching.yoda

Final best measurement: M_W = 80.3945 GeV

True W mass reveal: M_W = 80.4 GeV

Congratulations: The Herwig group wins!
