ElieHammou · 2026-04-22T15:33:36Z

This PR aims to implement the projections for the different descoped FCC-ee scenarios

To do:

Generate measurements projections for short descoped run with updated lumi
Generate measurements projections for short descoped run with updated syst
Recompute parametric uncertainties

Copilot

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Adds a “descoped FCC-ee” dataset pack: new theory response tables (JSON), projected measurement inputs (YAML), and inverse-covariance matrices (DAT) to support the descoped implementation referenced by the PR title/description.

Changes:

Added new theory/descoped_*.json files containing SM baselines, scales, and LO EFT coefficient responses for multiple FCC-ee observables and energies.
Added commondata_projections_L0/descoped_*.yaml projection datasets (central values, lumi, stat/sys uncertainties, metadata).
Added external_chi2/optimal_observables/invcov_descoped_*.dat inverse-covariance matrices used by the “optimal observables” inputs.

Still need to:

Remove the observables not planned in the descoped version
Address the external likelihood with a hardcode covmat
Figure out the relevant luminosity rescaling

…% lumi

ElieHammou · 2026-04-23T12:58:55Z

Need to merge Jaco branch in this PR

Then move to the new subfolder

ElieHammou · 2026-04-28T10:08:44Z

Hi @jacoterh ,
I noticed that you have duplicated all the datasets into the new folder, including the LHC ones. Is this how you think it is best to proceed?

jacoterh · 2026-04-28T14:13:33Z

Yes, because we can only link to a single commondata directory at the level of the runcard so the LHC ones need to be there

moatms · 2026-04-29T09:26:02Z

Just to clarify the new structure of the commondata folders:
-commondata_projections_descoped_fccee_short_run: short descoped fccee
-commondata_projections_descoped_fccee_4ips: in the draft we have "lower beam power and the absence of top run", which luminosity is assumed there then?
-Long descoped FCCee: we use the default commondata_projections_L0, and modify the parametric uncertainties on mt in the theory folder

Descoped FCCee with a staged top run: We include the staged top run datasets for the short and long descoped fccee scenarios in the "commondata_projections_descoped_fccee_short_run" and "commondata_projections_L0" folders respectively.
Is that right?

ElieHammou · 2026-05-19T13:25:23Z

I think the lumi for commondata_projections_descoped_fccee_4ips is 60% of the full run

ElieHammou · 2026-05-19T13:29:26Z

What is the difference between long descoped FCC + top run and the full FCC already?

moatms · 2026-05-19T13:43:41Z

I think for the difference between long descoped FCC + top run and the full FCC, it depends how long you let your top run be for in the descoped scenario. If the top run is long enough then it will reproduce FCC-ee. Another scenario is to imagine a top run in the descoped scenario which would last as long as in the full FCC-ee and not longer (to save money), and then with less beam power we'd get a reduction in luminosity of a factor of 0.6

moatms · 2026-05-19T14:17:25Z

The OO still need to be updated right? It looks the same as the non-descoped file

And similarly I see in the script [rescale_descoped_fccee.py‎] that the tt datasets have not been rescaled, that's completely fine but we need to remember that

I assumed that the rescaling would be done by the interface_oos_descoped_fccee.py script. Is that not so?

Where I actually have the wrong file name I guess...

Umm but can the OOs just get rescaled with the luminosity? I'm not sure how they're exactly implemented, but @ecelada you might know?

I mimicked something that was already done for LEP3 I believe
I would assume this supposes that uncertainty is stat dominated?

Indeed, the uncertainty on the OO is only statistical

moatms · 2026-05-19T14:20:32Z

Are these the new numbers with mW=80.3692?

No idea, I rescaled from whatever what in main when I opened the PR

But why is the best_sm changed?

Because we need to merge #132 which also updates central values. It will affect files in the commondata_projections as well

So are the numbers currently in FCCee_Zdata in PR 138 with mW=80.3692 (the new mW) or why did they change from the values in "main"?

the value in this PR haven't been updated yet as far as I know, but I updated them in the json cause we need to update them everywhere

But where would they enter except in the Zpole json file? You're saying you updated the values in FCCee_Zdata with the new mw value right?

yes this is only about the Z pole

moatms · 2026-05-19T14:48:56Z

The same file in "main" has diagonal terms which are negative (for example the first one, -7.068549381966553e-05), while here they are positive. I am not sure it should be the case?

moatms · 2026-05-19T14:49:31Z

The diagonal terms disappeared here
