Suppose we consider a proton where we set the electric charge of the three quarks towards zero. At this point I assume we still would have the three quarks bound together? Now reduce the strength of the strong force by say ten times. I was told in posts that the radius of the proton depends on the strong coupling constant like, r ≈ exp(c/g) or r ≈ exp(c/g^2) Can we assume the mass of the proton is dependent on the strength of the strong force? Quarks polarize the vacuum by two countering effects, virtual quark and virtual gluon production? As the strength of the color force is reduced is the reduction in the polarization of the vacuum proportional between virtual quark and virtual gluon polarizations? Is there some type of scale invariance here, do they both go to zero at the same rate? Thanks for any help!
