@Anonymous So let's say we have a
pentaquark. You ask "what are the chances
it would shift the length of one quark to the right?". What do you mean by "
it"? Also, what do you mean by "length of quark"? In QCD, quarks are point-particles with zero size, and experimentally they have been confirmed to be no bigger than 10^−19 meters in size. You are wondering about how to calculate a shift in length from 1 x 10^−20 to 2 x 10^−20?
