@WKCosmo It's all about magnets! If there were a magical way to safely produce and operate magnets at (say) 100T, the reachable energy scale even with the LHC tunnel would increase drastically

@WKCosmo hep-ex people seem to take this as a hard constraint and blame material scientists for it, instead of trying to put extra effort into this R&D
English
"I refuse to even consider this because it will encourage bad people" is an argument that should be eliminated from scientific discourse. It is the opposite of a scientific mindset.

@WKCosmo Her job is maximizing YouTube views for a general audience now and this is red meat for the science denial crowd - ‘they think you are too stupid to know any better.’ Yes, a gen audience absolutely has no idea. this is why we have RFK now youtu.be/6P_tceoHUH4?si…

Exciting! The Belle experiment sees evidence for a charmonium strange pentaquark that was seen by LHCb in baryon decays. They see it in Y(2S) decays, do not in weak decays of the b quark. A very different production mechanism. ⚛️🧪

Checking for energy conservation is now optional before submitting to arXiv? arxiv.org/abs/2502.05495

@PKoppenburg or a trick to bypass the work permit system for foreigners?
English
Apparently this concept exists in some universities. A trick to get tuition fees forever?

What is dark matter? 🤔 We asked Erwan Robyn, a postdoctoral student, to tell us what is this mysterious matter that makes up 85% of our #Universe, and how is the Alpha Magnetic Spectrometer (AMS) experiment looking for #DarkMatter. Curious to know more? Are you currently in the Geneva (Switzerland) area? On 31 October at 19.30 CET, CERN organises an immersive evening that will take you on a journey from cosmology and #ParticlePhysics to neurosciences. Join us to celebrate #DarkMatterDay at CERN: indico.cern.ch/event/1449536/

Could we PLEASE stop hyping every 1.5 sigma excess as "a hint of new physics"? This is seriously damaging the reputation of the field once all these excesses go away.

@WKCosmo Back in my days, the undergrad particle physics course said "top is too short-lived to form bound states". It's like finding a stamp from Czechoslovakia emitted in 2024. Rewriting the textbooks should feel cool.
English
All science is either physics or stamp collecting. Also, physics is now stamp collecting.

The CMS experiment just reported evidence of a scalar top anti-top bound state! cds.cern.ch/record/2911775

@PKoppenburg so it's similar to the relative rate of Higgs production compared to the total pp cross-section at the LHC?

"This measurement relies on identifying the one-in-10-billion K+ decay that is our signal and making sure it is not one of the other 9 999 999 999 decays that can mimic the signal,” says lead data analyst Joel Swallow.

The animation for the 20th aniversary of @getindico was quite fun to see on the 43 first indico pages I opened. But now it's getting slightly predictable.

@DavidMarzocca @will_pietrak @FCC_study They will eventually rename it to Flagship Cern Collider and get away with that
English
@will_pietrak @FCC_study I don’t know, but what are we waiting for? The longer it is used the harder it will be to change it. I’m not sure if it’s not too late already
English
FCC-ee is quite a bad name, it implies it will remain forever in the future. Perhaps we should go back to the original TLEP (Triple LEP)? Or better, VLEP (Very Large Electron Positron) collider? Something else? @FCC_study

@PKoppenburg @WKCosmo interestingly, this comment also applies for the CMD3 measurement of the HVP
English
@WKCosmo A measurement that is inconsistent with everyone else including with past yourself is not called an anomaly.
English
Not looking good for the W mass anomaly from CDF. The Standard Model wins again.

@DrAndreDavid every seven hours there is a PhD student submitting their thesis with this citation in the first chapter :)

@PKoppenburg @cajohare Someone recently pronounced it as 🦆-matter, and now I can't unhear it.
It seems we are approaching the 🦆matter🐸
English
I am reading @cajohare's "🐸 on the horizon" paper and my brain replaces each instance of fog by 🐸. I wish it stopped doing that.

As if Xenon dark matter experiments didn't already have enough to worry about

@PKoppenburg @MRiwu_u this one is only 3He while they also see a different state with 4He?

@JimBaggott Why did i read it as "Quantum Obama" at the first look

@SebViret @PKoppenburg @Tristan_duPree This is not even a "publication": not even submitted to arXiv

@PKoppenburg @Tristan_duPree CMS and ATLAS publication processes are really getting too slow 😅

@DrAndreDavid @CERN @Fermilab @kek_en a somewhat popular narrative among Chinese scientists is that the sustainability discourse is imposed by Europeans in order to limit Chinese economical/scientific growth
English
Only @CERN DG tackled this question, with the directors of @Fermilab, @kek_en, and #IHEP directors saying nothing on the matter.

Q: Do we do enough for sustainability? Fabiola: In these things you never do enough, we can do more. However there's been growing awareness. Our field can model worldwide collaboration, tech development, would be nice to be model of sustainable research.

This thing of private list of participants or no online list of participants should end here. Come on, conferences exist with the purpose of talking with colleagues, if you don't know who'll be there how the hell are you supposed to know if you are interested in being there?
