Honestly baryons got a little kick to em

Today the LHCb collaboration posted a #preprint on the first observation of CP violation in baryons. What's the matter?

To be slightly more explicit: "matter" comes in the form of baryons (protons, neutrons, etc) and leptons (electrons, neutrinos, etc) and their antiparticles. Observation indicates that there are many more baryons than anti-baryons in the universe - the "baryon asymmetry." We're not sure why.

New result from CERN (@lhcb.bsky.social) finds CP violation in the decay of baryons for the first time. Not unexpected - and not violation of baryon number itself! - but hopefully one more step in understanding why there is more matter than antimatter in the universe.

CERN Physicists Find Key Piece of the Matter-Antimatter Puzzle
In a first, CERN physicists succeeded in observing matter-antimatter imbalance in baryons, fundamental particles that make up most of the observable universe.

Piecing the matter–antimatter puzzle together 🧩

Last week, the @lhcb.bsky.social announced the observation of CP violation in baryons.

Evidence for matter-antimatter asymmetry in baryons from @lhcb.bsky.social . 🧪
Study of Λb⁰ and Ξb⁰ decays to Λh⁺h′⁻ and evidence for CP violation in Λb⁰→ΛK⁺K⁻ decays arxiv.org/abs/2411.15441 - Evidence is found for CP violation in the Λb⁰→ΛK⁺K⁻ decay, interpreted as originating primarily from an asymmetric Λb⁰→N*⁰K⁻ decay amplitude.

CP violation, baryons, mesons, neutrinos, oh my!

I watched the defense today and it was the most fun I’ve had listening to someone talk about baryons in an astrophysical context, maybe ever! Congrats to Dr. Omoruyi 🔭🧪
Warmest congrats to former SAO Astro REU student *Dr* Osase Omoruyi, seen here with her excellent PhD advisor Dr Grant Tremblay celebrating her successful thesis defense today.

Les protons et les neutrons font partie de la famille des baryons, c'est-à-dire des particules formées de 3 quarks.

Ils en sont les plus connus, les plus stables, mais il existe bien d'autres baryons, qui sont toujours la combinaison de 3 quarks.

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

In a universe with only baryons and hardly any anti-baryons it's bizarre that we don't find any CP asymmetry in baryon decays. Now we do. 👏 @lhcb.bsky.social

It's not only lithium, but half the baryons themselves seem to be missing

So anyway this experiments measures a particular *type* of CP violation - in the decay of baryons to other baryons. Expected in the standard model, but it's good to measure it, and hopefully the more measurements we do the closer we will come to understanding how all this works.

Now on @sciam.bsky.social: The Large Hadron Collider has, against considerable odds, detected a long-sought asymmetry between matter and antimatter (CP violation) in subatomic particles called baryons. Our own @clarakm.bsky.social has the news.

In #Cosmology, the loss of antibaryons happened when the universe was over 10^12 Kelvin and only 10^-4 seconds old. The remaining baryons survived because of the baryon-antibaryon asymmetry of the universe which is still a great mystery in #Physics #Science #Astronomy 🧪⚛️🔭 doi.org/10.3390/univ...

For those that can't math.

Does one human body comprise the known universe?
(Hint, the answer is not "yes".)

Is each bacterium made up of at least one atom?
(Hint, the answer is not "no".)

For mathies :
baryons = 10^80
baryons / bacterium = 10^13

Here we see the TWOCRYST experimental setup at the #LHC.

This innovative experimental concept aims to measure the properties of charm baryons using a fixed target and two bent crystals.
September 8, 2025 at 7:28 AM
Is there also a difference between baryons and anti-baryons? So far we haven't seen any. (We had a hint a few months ago.)

Today we have a clear signal.

The first experimental evidence of the breaking of charge–parity (CP) symmetry in baryons has been obtained by CERN’s LHCb Collaboration. 🧪⚛️ ow.ly/Hrw650Wrmhh
CP violation in baryons is seen for the first time at CERN – Physics World
LHCb result is consistent with the Standard Model, but could provide a path to new physics

LOL I am going to use this next time someone says “everything happens for a reason” thank you

I could also have gone with "not all baryons"...

Try rerouting baryons from the main deflector array.

SPACE FACTS: DAY 22/365🧪🛰

Everything that you see is made up of something scientists call "baryons"—basically, all atoms are made of baryons. But this baryonic matter is only **15%** of the total mass in the universe. That other 85% is a currently undetermined stuff that we call “dark matter.”

it’s like baryons
