Observation of charge-parity symmetry breaking in baryon decays: arxiv.org/abs/2503.16954 -> Why is there more #matter than antimatter? CERN result offers tantalizing new clue: nature.com/articles/d41586-025 - physicists have spotted a difference in the way matter and antimatter baryons decay, which could help to explain a major cosmic mystery.

arXiv.orgObservation of charge-parity symmetry breaking in baryon decaysThe Standard Model of particle physics, the theory of particles and interactions at the smallest scale, predicts that matter and antimatter interact differently due to violation of the combined symmetry of charge conjugation ($C$) and parity ($P$). Charge conjugation transforms particles into their antimatter particles, while the parity transformation inverts spatial coordinates. This prediction applies to both mesons, which consist of a quark and an antiquark, and baryons, which are composed of three quarks. However, despite having been discovered in various meson decays, $CP$ violation has yet to be observed in baryons, the type of matter that makes up the observable Universe. This article reports a study of the decay of the beauty baryon $Λ^{0}_{b}$ to the $p K^{-} π^{+}π^{-}$ final state and its $CP$-conjugated process, using data collected by the LHCb (Large Hadron Collider beauty) experiment at CERN. The results reveal significant asymmetries between the decay rates of the $Λ^{0}_{b}$ baryon and its $CP$-conjugated antibaryon, marking the first observation of $CP$ violation in baryon decays, thus demonstrating the different behaviour of baryons and antibaryons. In the Standard Model, $CP$ violation arises from the Cabibbo-Kobayashi-Maskawa mechanism, while new forces or particles beyond the Standard Model could provide additional contributions. This discovery opens a new path to search for physics beyond the Standard Model.

#homeassistant integration recommendation of the day:

"This project simulates bridges to publish your entities from Home Assistant to any Matter-compatible controller like Alexa, Apple Home or Google Home. Using Matter, those can be connected easily using local communication without the need of port forwarding etc."

I am not using this integration myself, as I don't own any #Matter devices (yet?). But I read many good things about it. Seems to be one of a kind.

#Microsoft now says it has created a new state of #matter in its quest to make a powerful machine, called a #quantum #computer, that could accelerate the development of everything from #batteries to #medicines to #AI.

On Wednesday, Microsoft’s scientists said they had built what is known as a “topological qubit” based on this new phase of physical existence, which could be harnessed to solve mathematical, scientific & technological problems.

🇬🇧 I just finished the #electrical installation in my new house. All that's left is to install the sockets and switch once it's painted, but the wires in the boxes are already connected and the #Shelly 1PM/2PM Gen3 smart modułem (the ones that support #Matter ) are also installed. Will there be any takers for a #blog post describing the whole process of installing this?

🇵🇱 Właśnie skończyłem instalację elektryczną w moim nowym domu. Zostało tylko zamontować gniazdka i włączniki na gotowo, gdy będzie już pomalowane, ale przewody w puszkach są już połączone i zainstalowane są też inteligentne moduły #Shelly 1PM/2PM Gen3 (te wspierające #Matter ). Czy znajdą się chętni na wpis na blogu opisujący cały proces instalacji tego?

Smart-Home-Standards gibt es viele. Für Handyhase habe ich versucht das Ganze etwas verständlicher aufzubereiten. Bei der Masse ist das leider nicht so ohne Weiteres möglich und leider hat jede Kommunikationsart so ihre Vor- aber eben auch Nachteile. Dank Matter lässt sich das aber zunehmend zusammenschalten.
