As the title says- what is it that makes all mesons unstable? I know some quarks are less stable than others obviously, but why is there no stable meson? What is it about any combination of quark and anti-quark that makes a particle decay nearly immediately?
In a related topic- what exactly is it about uud that makes a proton stable?
Thank you in advance to any respondents.
