[edit] Mass

Since no quark can exist in a free state (ie, unbounded to another quark), how can we claim a single value for the bottom quark's mass? Its effective mass is going to be different depending on which meson it's in, just like the effective mass of protons in a nucleus are not equal to the mass of a free proton. We should make a note of this where we give the mass, no? Miraculouschaos 16:26, 1 August 2007 (UTC)
