Optimizing VBF at NLO
Hi Folks,
I am aiming to generate a very large and healthy VBF at NLO+PS dataset and wondering if there are any recommendations for optimizing speed and phase space integration.
To be precise, this is not the usual WW or ZZ fusion but W\gamma fusion with an initial-state photon, i.e., q a > q BSM, following the procedure of [1]; See Eq (20).
[1] https:/
So while the color structure is marginally simpler than WW/ZZ fusion (my color structure is actually identical to Fig 1c in [1]), I am still dealing with a 2 > 4 system (only one final-state quark). Some optimizations I am considering include
- setting #IRPoleCheckThr
- activating nevt_job
Are there other (potentially more reasonable) optimizations anyone may recommend, e.g., collier vs ninja, etc?
Many thanks for looking into this!
Best,
Richard
