law of baryon conservation

The law of baryon conservation is a fundamental principle in physics stating that the total number of baryons in an isolated system remains constant, even when particles transform or decay. Baryons are subatomic particles composed of three quarks, with protons and neutrons being the most common examples. This conservation law explains why protons, which have a baryon number of 1, are incredibly stable and do not decay into lighter particles with a baryon number of 0. While other heavy baryons can decay into lighter ones, the total baryon count remains unchanged. This principle is considered exact and has been extensively searched for, but no violation has been found.12345
