13 Default Powheg configuration for opposite-sign W-boson pair plus jet pair production through vector boson fusion.
15 Create a configurable object with all applicable Powheg options.
17 Note that in the presence of a very sharp resonance, as is the case in a scenario with a light Higgs boson with a
18 mass below 200 GeV, the resonant Higgs contribution has to be evaluated separately from the WW continuum, as
19 described in https://arxiv.org/abs/1301.1695. In this case the entire event generation chain has to be performed
20 for each of these two contributions separately in two distinct working directories, setting
21 :code:`PowhegConfig.ww_res_type = 1`
22 for the WW continuum and
23 :code:`PowhegConfig.ww_res_type = 2`
24 for the Higgs resonance contribution. After all the runs have been performed for each case, the results have to
26 If the Higgs is heavy and broad, such a splitting is not necessary, and all contributions can be evaluated at the
28 :code:PowhegConfig.ww_res_type = 0`.
