The pion [tex]\pi[/tex]+ has the same quark content as the rho[tex]\rho[/tex]+, but different rest mass. Why is that? And does the same apply to the [tex]\pi[/tex]- and [tex]\rho[/tex]-. Will they have the same mass difference?(adsbygoogle = window.adsbygoogle || []).push({});

Thanks for your help!
