Energy pie chart for proton, field energy?

  1. Jul 31, 2011 #1
    Can the energy in the fields that make up an proton be fraction-ed into a pie chart?

    Don't we have quark, gluon, weak, electromagnetic field energy in a proton?

    Thanks for any help!

    Think of it as all gluons and you'd be pretty close. Surprisingly the quarks contribute only a percent or two, all the rest comes from gluon binding energy and kinetic energy.

    Thank you!

    How wrong would I be if I estimated the Electroweak field energy contribution by the relative strength of the forces:

    Strong field energy:Weak field energy:Electromagnetic field energy::

    1:1/137:10^-6 or should it be the squares of these numbers?

    Numbers from:


    Thanks for any help!
