Question
Disregard binding energies and estimate the masses of the $u$ and $d$ quarks from the masses of the proton and neutron.
Step 1
Protons and neutrons, which are nucleons, are each made up of three quarks. Specifically, a proton is composed of two up quarks (u) and one down quark (d), while a neutron is composed of one up quark (u) and two down quarks (d). Show more…
