  1. Mesons, bug or understanding? by dpilot · · Score: 5, Interesting

    According to the table, the pion and rho mesons both seem to be built out of an up and an anti-down. Both have a charge of +1, but the masses and spins are different.

    To answer my own question, a quick google shows:
    http://hyperphysics.phy-astr.gsu.edu/hbase /particl es/meson2.html

    The quick answer - The rho meson is an excited pion.

    After a quick look, the hyperphysics web site looks quite interesting. This is the starter link:

    the high-res versions that are offered here are great. i have access to a huge hp designjet, and plan on printing these out for office wall art. does anyone know of other sites that offer similarly good, free, printer-quality sciency images?
