Hi all,
So quarks are given fractional charges, which then add to the total charge of the particle they constitute. My question is if the electromagnetic forces between quarks are taken into account? I was thinking that such things might be automatically taken care of via Feynman diagrams etc, but I don't think QFT deals well with bound states...
As a side point, presumably there is then a charge distribution inside particles, depending on the charges of the quarks. Is there empirical evidence showing effects of this? I presume it does not show up in things such as the hydrogen spectrum as the electron is sufficiently far from the proton for it to be negligible...?
All thoughts appreciated.
