Excited to share the first results using Neural Simulation-Based Inference (NSBI) techniques applied to @ATLASexperiment data! We measure the elusive off-shell Higgs boson with 3.1x better observation sensitivity than standard (histogram) analysis techniques! A thread: (1/N)

Physicists at the ATLAS Experiment at @CERN release a new study of the Higgs boson interacting with top quarks! 🔍 Studies of this rare process can give us insight into the origin of mass. Check out our new briefing to more⤵️ atlas.cern/Updates/Briefi…

The ATLAS Collaboration celebrates the International Day of #WomenInScience! The collaboration stands with all young women and girls who want to pursue a career in STEM. Here are just some of the women of our collaboration, who are working to push the boundaries of our knowledge.

@GregorKasieczka @pietrovischia Yeah, that was it! Thanks for the link. I was wondering whether it was compatible with the Iris-HEP grand challenge framework, and it seems to be, at least from what's shown in Marcel's slides.

Sad drift of big sci collabs towards company-style centralised analysis code: horrendous pedagogically (whereas the backbone are PhD students, so the pedagogical aspect should be preferred over company-like goals), and one step further towards stripping individuality from process

@agbuckley I was curious if a unicode θ̂ might help, but not so much (perhaps I would need to encode it differently though).

I understand the bad join (it's two separate lines without mitre; maybe an easy fix) but weirdly the hat x,y positions are symmetric in the code but are obviously asymm on canvas. Is any *data* being similarly mangled by the rendering system? We'd have seen it, right?

Still blows my mind that non-shit typesetting in plots is an 20-year unsolved technical issue for the community that built the LHC

@phi_nate Too many levels could also indicate that a split at a higher level (into a different (sub)section) might make sense.

@phi_nate It can be more readable in my opinion to not use numbers with the lowest level subsection, as you are typically still close enough to a higher level (with numbers) for orientation. (Unless those subsections are still multiple pages long.)

@HEPfeickert @iris_hep Thanks for the kind words! I am grateful to be able to showcase this project, which is made possible by the many people working on the facilities, services, and libraries we are using.

This was an amazing presentation both in its technical scope and in @alheld_'s perfectly paced and scoped delivery. Truly exceptional! I'm of course biased, but these talks make me very excited about the physics that @iris_hep is enabling for the HL-LHC and even now for Run 3!🚀
