CERN's Large Hadron Collider finds the heaviest antimatter particle yet

[zohaibahd]

Yeah! Science! Scientists at the CERN Large Hadron Collider – the most powerful particle accelerator ever built – have detected the heaviest form of antimatter observed. This discovery is as important as CERN's previous breakthroughs, like the Higgs Boson particle, B-meson decay, and hypernuclei.

Scientists from the ALICE (A Large Ion Collider Experiment) at CERN's Large Hadron Collider reported evidence of a new antimatter particle called antihyperhelium-4, essentially the "evil twin" of another weird particle called hyperhelium-4. This incredibly exotic form of matter contains two antiprotons, an antineutron, and an unstable particle called an antilambda comprised of subatomic quarks.

This discovery is important because it allowed physicists to study the extreme conditions of the cosmos when it was less than a second old. It also gives us insights into one of our biggest mysteries: the baryon asymmetry problem.

When the universe burst into existence during the Big Bang, matter and antimatter should have existed in equal amounts. Since the opposing pairs always annihilate each other, all matter and antimatter should have converted into pure energy. Somehow, we ended up with a universe dominated by regular matter, with just a tiny bit of antimatter surviving. Studying hyperhelium and its antimatter twin could help unlock this puzzle.

The discovery of antihyperhelium-4 resulted from a collision experiment performed with the LHC in 2018. It slammed together lead ions at stupendous speeds, recreating the hyper-hot conditions of the newborn universe. Researchers then used a cutting-edge machine learning model to study the data from the collision. The analysis spotted the signature of antihyperhelium-4 particles as they decayed into other particles.

Also spotted was the lighter antihyperhydrogen-4. The researchers precisely measured the masses of these two particles and were able to match the data with the most current physics theories. The experiment's results confirm that matter and antimatter are created in equal portions. So, what tipped the balance if the universe started with level proportions?

Physicists are still without adequate answers. However, the LHC receives occasional upgrades, like the one that installed supersized magnets for sharper beams earlier this month. Who knows what new antimatter extremes may emerge next?

This discovery is as significant as CERN's previous breakthroughs, like the Higgs Boson particle, B-meson decay, and hypernuclei.

In the world of click-driven reporting, a certain degree of exaggeration is to be expected, but this whopper really goes beyond the pale. The discovery of the Higgs Boson was the first direct experimental proof of the Higgs Field; the reason mass exists in the universe. Nor were hypernuclei discovered by CERN, but have been seen by researchers since the 1950s.

Vis a vis the Higgs boson, this development isn't a hundred-thousandth as important. Once we knew hypernuclei existed, we knew each would have its own antiparticle. This is significant only if we can analyze its decay patterns to potentially gain insight into the baryon asymmetry problem.

In fact, Ahmed missed entirely the most relevant portion of this story. The "find" was made by using new AI-driven machine-learning techniques against old data that CERN first collected back in 2018. Analyzed the traditional way, the particle was invisible.

Well when they can say with some certitude why normal matter dominates, that would be as big - then leave it to experts which is bigger- Again that would be kind of meaningless - which is more important to make std bread water or flour. You can't have bread with absence of either.

More curious why a super rare particle than a common one with atomic number of three , I suppose easier to add to helium than next element up . Ie the universe would be awash with these if they were stable. eg Sun probably makes these along with std helium all the time. Ratios in Sun probably have some correlation here

Reminds me of a one panel cartoon I once clipped. A lady has recorded herself on her husbands new video gear. She is on the TV asking him, "And how much did this cost?"

ah here come the fake-made-up-undead-magik-hippie science hating people to decry a project that costs the US less than 1.5 F22 jets ... republicans ... smh

I never wrote that it is money ill spent. I bought the video gear. I related a memory and something that made me laugh. Temper your anger, Oh, I am a proud conservative.

This is great and all but let me know once they've got something making power instead of using it.

Wow, you really embarrassed yourself there. The US spent billions on the Supercollider project -- a larger, more capable version of CERN -- only to have the project cancelled by a bill written by Democrat congressmen Jim Slattery, and signed by Democrat Bill Clinton. If not for them, this new particle would have been discovered in the US, not Europe ... and many years earlier.

The issue goes back even further, as the best-known firebrand against US big science projects was Democrat Senator William Proxmire, who in the '70s and '80s worked tirelessly to end all NASA space missions entirely, and was successful in getting many of them cancelled.

So, what tipped the balance if the universe started with level proportions?

...because the programmer spotted their error

10 IF Y>X THEN Y=X-1
20 GOTO BIG BANG
30 END

There is a global shortage of Copium. I feel for you.

According to Occam's Razor, could it be that the asymmetry indicates that the universe did not start with the Big Bang? There was an expansion, but that's the only similarity between what actually happened and the current description of the hyperspherical Big Bang.

This entire fiction is just a hilarious shell-game and advertisement. Particles and their "anti-particles" are simply upside-down to each other in spin, and in a collision cancel out one spin in their redirection, or spin each other up. There's no such thing as "annihilation" or "pure energy" without mass. It's in every energy equation already.

E=mc²
Energy = mass * the speed of light linearly * the speed of light's spin at the tangent

You cannot have energy without mass. It's the measure of a collision, not a physical or tangible object. Energy measures the amount of momentum transfer between two (or more) masses. Even photons have mass. Everything that exists has mass, or else it does not exist at all.

There is no such thing as "hyperhelium" or "hyperhydrogen". There's also no such thing as "antilambda" particles or quarks at all. They've never existed and were just contrived to fill holes in the shoddy physics, to sell more fake tests and expensive, useless devices. Slamming an alpha with another neutron doesn't make it a new particle - it's a helium atom that briefly contained an extra neutron or proton before that spare particle was spit out by the ambient charge field.

Just like the fake Higgs boson being simply a proton with a few stacked spins, and thus unstable in the charge field and prone to being de-spun back to a proton or neutron, this entire article is clown shoes. Written by scammers and not a drop of physics to be found.
