Hi Stephane,

"The Run2 resolved VBF … is responsible for the majority of the sensitivity to SM VBF-HH production as well as kappa-2V scenarios near SM (the merged is not really sensitive). …."

• We see the sensitivity is completely driven by (Run2-boosted + Run-3). The Run2 resolved has only a 4% effect on the sensitivity to SM VBF-HH production.
• The relative impact on the k2v is shown below [1], here the CL is dominated by Boosted, with the Run2 resolved with a small effect.

"Alejandro’s slides make the point pretty clearly that these issues do have a real quantitative impact on the results presented, at the level of about 4% for the Run2 + Run3 mu_VBF"

• Its true the impact is quantitative, but it is small. Our combined sensitivity to mu_VBF is 100xSM, this is an exotics search. The change is mu=99 -> 103; it is real, but I dont think very important. The uncertianties (largely statistical) on these numbers are 10x bigger than the difference we are talking about. So we have a ~ 0.1 sigma effect on mu~100, for the "secondary" measurement of the paper (kl and ggF being the primary).

I like your point about not mixing and matching different strategies. So I think we should include the new VBF signal samples in the Run-2 resolved re-analysis (Option c above). This solutions is straight forward and should be relatively quick.

• Good runs.. played well … All wins… covering spreads

• See logs above
