Thank you, it's worth a look for sure.

Good (PBS) summary.

It's not the new chatbots in the news (Large Language Model / Generative stuff), like chatGPT, which are known to hallucinate.

It is a deep learning network trained on 30 years of experimental data, and a large collection (100's of thousands) of theoretical models.

It comes up with the "best" model that fits the experimental results.

Right now, "best" at the "3 sigma" (1 in a 1000 chance of being wrong) which is the "very interesting, but ..." level of proof.

Burp. More data, please.

Sabine Hossenfelder is a vocal critic of the way things have been conducted. She is not popular among her peers for the same reason. At some point employment security becomes more important than the search for truth. These massive projects create a lot of loyalty among the ones working there.

(I think ITER falls in the same category as CERN, BTW).

Evidence for intrinsic charm quarks in the proton - Nature

Through machine learning analysis of a large set of collider data, a study disentangles intrinsic from radiatively generated charm, and finds evidence for an…

the charm quark is expected to have a fleeting existence .t.<<<10(-20) seconds?

which the lifetime of the garbage exceeds by a tad

"Here we present a resolution of this four-decade-long conundrum by providing unambiguous evidence for intrinsic charm in the proton.

This is achieved by means of a determination of the charm PDF (ref. ³) from an extensive hard-scattering global dataset,

using state-of-the-art perturbative QCD calculations¹⁹, adapted to accommodate the possibility of massive quarks inside the proton^4,20,21, and sophisticated machine learning techniques^3,22,23. This determination is performed at next-to-next-to-leading order (NNLO) in an expansion in powers of the strong coupling, α_s, which represents the precision frontier for collider phenomenology"

Number fudging extraordinaire.

precision frontier for collider phenomenology

There is ambition to explain medium mass nuclei such as 73Ge gamma spectrum..by QCD

maybe even the lowest energy state at 13 .....kev

sadly, the QCD deuteron modelling is a bit off...by 10 Mev or so.. not so precise

a few more decades of fudging might get it right.

. or not..
