Dirac equation for the proton (II) -- Why fractional charges for Muster Mark's Quarks?

Abstract

The present reading is the second in a series where we suggest a Dirac equation for the Proton. Despite its great success in explaining the physical world as we know it, in its bare form, not only is the Dirac equation at loss but fails to account e.g. for the following: (1) Why inside hadrons there are three, not four or five quarks; (2)Why quarks have fractional charges; (3) Why the gyromagnetic ratio of the Proton is not equal to two as the Dirac equation requires. In the present reading, we make an attempt to answer the second question of why quarks have fractional charges. We actually calculate the exact values of the charges of these quarks.
