> Physicists at the world’s largest particle accelerator have made a first-of-its-kind discovery about antimatter that could help solve one of the universe’s biggest mysteries.
> The discovery — made at the Large Hadron Collider (LHC) at CERN, near Geneva — has revealed that a short-lived cousin of protons and neutrons, **the beauty-lambda baryon,** decays at a different rate than its antimatter counterpart.
> Called charge-parity (CP) violation, this effect refers to particles of opposite charge, like matter and animatter, behaving differently. It’s a crucial explanation for why matter was able to dominate over antimatter in the early universe. This violation has previously been only detected in particles made up of quark-antiquark pairs, called mesons.
> It has **not been observed in baryons** — three-quark particles, such as protons and neutrons, that make up most of the universe’s visible matter. This first-of-its-kind detection has changed that, potentially opening up an avenue to search for physics beyond the Standard Model.
> To search for CP violation in baryons, the researchers at the LHCb combed through data of the countless particle interactions (where protons collide roughly 25 million times a second) that occurred between 2009 and 2018.
> They tallied up the decays of the beauty-lambda baryon by searching for the telltale paths made by its decay products.
> This was measured to a statistical significance of 5.2 sigma, passing the the five-Sigma result physicists use as the „gold standard“ for heralding a new discovery.
> With the finding sealed, the physicists say they will look for even more CP violations when the LHC fires up again in 2030, and collect further data on the key mechanism that likely enabled our universe to exist.
I sort of understand this and the significance, plus it seems like a legit breakthrough… can I get the usual explanation from someone more educated that me on why this Live Science article is hyped nonsense?
Finally. Its like they discovered the higgs a fews ago and then nothing. Iv been following the lhc half my life. It was so hyped for nearly two decades. Then….nothing really happened. Good to see some progress finally being made. Im sure theres other things discovered that havnt made the news. But at this point i was expecting a lot more progress tbh.
