A new LHCb analysis confirms a previously observed tension with the Standard Model, but more data and improved theoretical calculations are needed to determine whether new physics is at play.

Do kaons decay using a new kind of physics? Researchers are trying to explain their anomalous findings. Their larger experiment is an ongoing investigation of CP symmetry. The anomalies could be ...

The η → e⁺e⁻γ decay channel holds particular significance for dark sector searches, as it provides sensitivity to dark photons and light protophobic X17 bosons that decay into electron-positron pairs.

Perturbative Quantum Chromodynamics (PQCD) presents a rigorous framework for disentangling the short-distance dynamics from non‐perturbative effects in heavy meson decays. Its application to B meson ...

The study of heavy flavour physics focuses on the behaviour of particles containing heavy quarks, such as the bottom (b) and charm (c) quarks, within the framework of the Standard Model and beyond.

Here’s what you’ll learn when you read this story: Do kaons decay using a new kind of physics? Researchers are trying to explain their anomalous findings. Their larger experiment is an ongoing ...

Scientists have proposed a new kind of subatomic particle to explain another particle’s mysterious disintegration. The kaon, a special case of meson particle, is made of one quark and one antiquark.
