Thanks @bonanomi , this looks great! Just some very minor comments here.

As discussed privately, I'll get on requesting a transfer of this and the signal sample in the near future. Thanks again for the work!

Is this the XS of XS(ZZ)*BR(Z->ll)**2? Might be good to write this out, or even have a look if e.g. the BR(Z->ll) is already part of the constants

[bonanomi]

Yes, this should be already xsec*BR. If we want to be 1:1 with the main HZZ analysis, we should consider adding the k-factors in the cf example to normalize this xsec to the NNLO one, but for the scope of the exercise this should be irrelevant.

hi @pkausw done in this commit

@bonanomi Is this PR still desired / alive, or did the POG exercise use your fork in the end?

[pkausw]

Just to comment: The PODAS exercise used this specific branch in the end.

Nevertheless, since we want to repurpose the exercise for the columnflow demo, it might be interesting to merge these samples into cmsdb so we can always use the latest and greatest version in the demo. What do you think?

[bonanomi]

Hi @riga , as mentioned by @pkausw we used this sample for the PODAS exercise. I am not sure if this qqZZ sample is going to be used by anyone else except for the HZZ4L example, but as @pkausw suggests, maybe this can be merged to make sure that we always use the latest greatest sample.

Sounds good. Then we should just merge after the above comment is resolved.
