Sihp data

[Radonirinaunimi]

This adds the single hadron production datasets:

Dataset names	paper	hepdata
PHENIX-2009_SHP_200GEV_PI0_ALL	paper	data
STAR-2006_SHP_200GEV_PI0_ALL	paper	data
PHENIX-2013_SHP_510GEV_PI0_ALL	paper	data
STAR-2013_SHP_510GEV_PI0_ALL-LOWRAP	paper	data
STAR-2013_SHP_510GEV_PI0_ALL-HIGHRAP	paper	data

These do not have the corresponding FK tables yet but we do have the codes to generate the predictions NNPDF/sihp-pp.

Please, rebase on top of master after I merge #2153

@Radonirinaunimi given that the naming convention is <exp.name>_<misc.info>, I think it would better to have years in the <misc.info> section instead of renaming the experiments to include the year.

[scarlehoff]

It depends whether the different years should be taken as separated experiments (when using per-experiment grouping for instance). So with STAR_SHIP_2006_200GEV_ALL all STAR would be grouped together, while STAR-2006_SHIP_200GEV_ALL groups the STAR-2006 dataset together.

(btw, for a moment I thought "Why do we have an 'all' observable, what does that mean?" 😆 )

I think these measurements might be also relevant (cc @enocera):

STAR 510 GeV: https://inspirehep.net/literature/1674826
PHENIX 510 GeV: https://inspirehep.net/literature/1789851

Charged hadrons (just for reference):
PHENIX 200 GeV inclusive: https://inspirehep.net/literature/1089402
PHENIX 200 GeV pions: https://inspirehep.net/literature/1315330

I've implemented them. The reference for PHENIX was not the correct one (it contains the charged measurements) and I rectified it in the table above. These measurements, AFAIU, were performed in ~2012-2013 but I just took 2013 for all of them.

Given that we'll not include this in the paper, I will not implement them now but rather do so once we have interfaced https://github.com/NNPDF/sihp-pp.

[Radonirinaunimi]

@scarlehoff please check that 7301318 address all the required changes in terms of having new process options.

And with this, modulo reviews, this PR is done AFAIC.

[giacomomagni]

Thanks @Radonirinaunimi, sorry for linking the wrong reference... to many papers indeed.
I'll have a look at the implementation asap.

[scarlehoff]

Thanks @Radonirinaunimi
do you want to wait until the grids are ready to merge it? (so that it is merged "completed" with the right grid names even if the fktables are not in the theory yet)

[Radonirinaunimi]

I think it'd be best to merge this as implementing the PineAPPL interface to produce the grids might take some time, mainly because we'll have to fix the C and Fortran APIs once V1-format is ready.

@Radonirinaunimi before merging, could you please add the identified hadron name somewhere in the dataset name or observable name (wherever you prefer). Having the PI0 mentioned explcitly in the names and not having to look in the metadata description would be super helpful especially when moving towards FF fits and preparing runcards.

Good point! Especially since for some experiments/measurements we have different final state hadrons. To conform with the other dataset namings (such as gauge boson production) I added the type and charge to the dataset name.

Thanks!
