Did you know that despite the claims that the Higgs Boson was the final puzzle piece of the Standard Model, there is another Standard Model particle that we have still never unambiguously observed? It isn't a quark or a gluon... So what is it?... Link: www.youtube.com/watch?v=srbC... ⚛️🧪
The Standard Model Particle We've Never Seen...and how to find it. [Re-post]

Me: Oh no! I printed in single-sided! All this paper wasted! 😱 Also me: Let's fix it by printing it again, double-sided.
Final readings of @lhcb.bsky.social papers: we have 7 papers these two weeks. And that's not yet counting the new results that will be shown at ICHEP. #LHCbEditorialBoard
I just heard someone at @cern.bsky.social say "tre milliarde lire" and now wonder in which millennium I am.
Looks like I'm now also on W. Let's see what this is good for.
Bjarne Stroustrup at CERN. The main Auditorium is packed.
These are hadrons number 84 and 85 observed at the LHC, of which 75 were observed by LHCb. The full list is maintained by @koppenburg.ch, see www.koppenburg.ch/particles.html .
This masterpiece, consisting of two VELO detectors with 46 Si modules in a row with an overlap of 4 mm and a mutual offset of 15 mm, can now be admired at @nikhef.bsky.social! It collected data from 2010 till 2018 in @lhcb.bsky.social @cern.bsky.social

Was there a glitch with @signal.org today? I just received all messages from the last 2.5 hours now.
Last week a paper in Nature claimed a detection of Gpc-scale anisotropic cosmic structures, violating the basic principle on which all #cosmology is based: www.nature.com/articles/s41... This week, a preprint says they made an elementary coordinate mistake: arxiv.org/pdf/2607.01172 🔭🧪 🧵 1/? ⬇️
Detection of anisotropic cosmic structures on a gigaparsec scale - Nature
Using the parameter-free Angular Distribution of Pairwise Distances for measuring directional correlations, evidence is found for coherent anisotropic structures extending over gigaparsec scales,...

Tour de France stage at CERN? Note that the stage will be 27km above ground. Not in the tunnel. 🤷 #TdF www.blick.ch/fr/sport/aut...
Le CERN en lice pour une étape du Tour de France 2029
Genève pourrait retrouver le Tour de France en 2029 grâce au CERN, qui fête ses 75 ans. La candidature prévoit un contre-la-montre de 27 km autour du Grand Collisionneur de hadrons.

So long #LHC and thank you for all the collisions 👋 Today, the Large Hadron Collider (LHC), the world’s most powerful particle accelerator, comes to the end of an extraordinary chapter in its scientific journey. Find out more: home.cern/cern-bids-fa...
If you think that @cern.bsky.social's LHC experiments have only discovered the Higgs boson - think again. So far @atlasexperiment.bsky.social, @cmsexperiment.bsky.social and @lhcb.bsky.social have discovered 85 new particles. @koppenburg.ch has been keeping count www.koppenburg.ch/particles.html

Dear #predatoryConference, thanks for the very personal invitation to the hypes in whatever field conference.

Welverdiende ERC-beurs voor theoreticus Juan Rojo van Nikhef en de VU. Hij wil het proton doorlichten met spookdeeltjes. www.nikhef.nl/news/advance...
Advanced ERC grant voor voorstel nieuw proton-experiment Juan Rojo - Nikhef
Het proton is een van de bouwstenen van alle materie, maar de bouw ervan is nog steeds niet goed begrepen. Nikhef-fysicus Juan Rojo gaat met een uitbreiding van...

Congrats to Juan Rojo ! 🎉
The results of the Advanced Grants 2025 are here! Out of 3,329 applicants, 319 leading researchers have been awarded an ERC Advanced Grant. Congratulations to all! 🎉 Curious to know more ? 👉 buff.ly/uiU9x5K #ERCAdG #FrontierResearch
The map shows Switzerland’s 4 national languages without the uninhabited high mountain areas. Suddenly the country’s linguistic geography makes more sense: German dominates the north and centre, French the west, Italian the south, and Romansh survives in pockets of the east. Source: buff.ly/NP7SzMs
