#Mesons
In my latest 🧪⚛️ column for @newscientist.com for subscribers (including libraries): beautiful non-binary mesons!

"the particles oscillate between being mesons and antimesons. In other words, neutral B mesons are spontaneously non-binary."

Why 'beauty factories' could solve two massive cosmological mysteries
Facilities that make particles called B mesons may seem obscure, but they could help explain why there is more matter than antimatter and what dark matter is, says Chanda Prescod-Weinstein

CMS explores subtle matter–antimatter difference using beauty mesons⚛️

The CMS experiment uses its largest sample of beauty mesons to date to perform a high-precision test of subtle differences between matter and #Antimatter

imagine living in the universe where all of the hundreds of other types of baryons and mesons are stable and they make their own atoms and elements and people have like >200 different periodic tables to keep track of

We've seen some differences. For instance in B mesons. They are particles containing a heavy b quark. Here's a plot of the number of B mesons (right) and anti-mesons (left) versus their measured mass.

I made a mass plot of the first reconstructed K short mesons in the initial collisions at the CMS experiment at LHC.

How B-mesons are threatening to break the Standard Model

There have been many "somewhat significant" (3σ+, but not 5σ) anomalies seen at the LHC to challenge the Standard Model.

Could this newest one, at last, be the one that sticks?

How B-mesons are threatening to break the Standard Model
We have very specific predictions for how particles ought to decay. When we look at B-mesons all together, something vital doesn't add up.

I'm only now learning about "vector meson dominance", a big idea put forth by Sakurai and others around 1960.

Just as the pion comes in +, - and neutral forms and has spin 0, the rho meson comes in +, - and neutral forms and has spin 1 - so it's described by a "vector", like the photon.

one of those short-lived mesons walks up and goes "Hey gu-" before they suddenly go poof and are replaced by a handful of other particles who just get up and wander off

The exact nature of the two mesons is still disputed. Are they tetraquarks? And are they unique? Can similar states be found in the b-quark sector?
September 24, 2026 at 9:00 AM
Things like pions are made of bonded quarks and antiquarks (they’re different flavors of quarks so they don’t annihilate with each other). There’s a whole category of composite particles like this called mesons.

The mass is the same in both panels (that would be a big discovery) but the amount of found (anti-) mesons is different: that's the peak height.
There are also small peaks that are different. These are Bs mesons, that also contain an s quark.

A third dimension appears with charm and anti-charm quarks. All the mesons in this plot have been discovered long ago.

In 1934, Yukawa wrote an article telling the force between two nucleons is due to exchange of mesons between them.

In 1947, mesons were observed in laboratory, strongly supporting Yukawa's theoretical prediction, which is considered a cornerstone of modern particle physics.

But these are mesons. They contain a quark and an anti-quark. Is this matter or anti-matter? You choose.

You absolutely cannot trust this guy, he seems like someone who would use a (+,-,-,-) metric.

This message was brought to you by mesons, exclusively from Big Quanta. Mesons: when you want a hadron but are a bit bored with baryons
Why hasn’t @mbkplus.bsky.social done a quantum mechanics and GR Coldplay kiss cam meme yet?

Only explanation: he’s in the pocket of big quanta.

In short, the light you see around you is subtly spiced by a slight mix of neutral rho mesons!

More precisely, real-world photons are a superposition of the "bare" photons we'd have in a world without quarks, and neutral rho mesons.

Why do we know this?
