There are mesons that change change. This is how there is a case put forth about why the universe holds only matter and not any antimatter. Holmlid got in trouble with particle physics for violating the conservation of baryon number. Protons and neutrons don't decay into mesons. But they should. This is called the Strong CP problem <https://en.wikipedia.org/wiki/Strong_CP_problem>. Particle physics has been looking for proton decay for years and when they find it courtesy of Holmlid they say that proton decay is impossible. These Physics professionals are hard to figure out.
