Implementation of future test data

[enocera]

The future test data sets, listed on the wiki, are assigned as follows:

dataset	c.m.e. (GeV)	L [fb-1]	arXiv	person in charge
W-boson production differential cross sections	13	140	2502.21088	EC + JK
W+jet production differential cross sections	13	140	2412.11644	KL + AP (on hold)
Z+charm production differential cross sections	13	140	2403.15093	TG + KL
W-boson production differential cross sections (low pile-up)	5.02/13	0.255/0.338	2502.09403	JK + AP (on hold)
W pT cross sections	5.02	0.1	2509.18817	KL+AP

As suggested by @juanrojochacon two new PhD students (+ Ella) are assigned to each data set. The idea is that they independently implement the data set, and then they converge on a common interpretation/implementation. This should be useful for them to be acquainted with the NNPDF commondata framework. @vschutze-alt : I have not assigned you any specific data set because you no longer qualifies as "new" PhD student, but you're more than welcome to help implement any of the data sets, if you'd like to do so. @ecole41 I have assigned only one data set to you. If you want more, just ask. The last data set in the table does not have a Hepdata entry yet.

Thanks @enocera this is most useful. Sounds like a great plan to me. We should also agree on a timescale to avoid that these things take too long - maybe we can say that by 1 Oct or so there is a first version of the common data implementation that can be cross-checked among the two assigned people?

For Z+charm, maybe @vschutze-alt can also help to speed up things?

Once commondata is implemented, the next step will be to generate NNLO grids, and also here I would adopt the principle that two people do an independent production and then they cross-check each other, in the long term this will save a ton of work.

I understand that progress in future test datasets will be discussed at the code meetings?

[juanrojochacon]

@jekoorn @kamillaurent let me know if anything is unclear, happy to discuss with you about the implementation process in the next days

[juanrojochacon]

Concerning the ATLAS 5 TeV and 13 TeV low-PU cross-sections: despite what Eram said in morimondo, indeed it is still not in in HepData. I will write to him how to see if he can speed up things.

Progress will be monitored during the weekly code meetings.

I was thinking the same - perhaps two people are not needed to take independent runs of the Monte Carlo, but it may be good to have two people independently implement the runcard which is then passed to a Monte Carlo. Note that in principle this is the mechanism of a PR review.

Yes

[juanrojochacon]

Well, I think it is still good that two people can carry out independent runs, maybe at low stats, and check that their results agree within MC uncertainties. Then yes, the final high-stats runs do not need to be repeated

[juanrojochacon]

but yes, one step at a time. I already emailed Eram about the missing HepData link, hopefully we will react fast

Hi, thank you for the assignment @enocera. I still don't have access to the wiki though

[juanrojochacon]

Maybe local Edinburgh people like @andrpie or @achiefa can help here?

[achiefa]

I don't have admin access to the wiki unfortunately.
I can ask Luigi in person when I see him, which will be next week.
Though maybe it would be better to ask him directly tomorrow at the meeting.

[enocera]

Anyways, access to the wiki is not needed to complete this assignment.

Hi, we've just checked that the data for 2412.11644 is not available online either. Could I work on something else in the meantime? Maybe 2502.21088 if @jekoorn or @ecole41 haven't started yet?
