The table below summarizes the properties of the various Standard Model particles and forces, except the Higgs particle. Masses are "current masses", and are given in electron volts (eV). 1 MeV is a million electron volts, and 1 GeV is a billion electron volts. The proton, for comparison, weighs ~938.3 MeV or nearly 1 GeV. Note that the "constituent quark mass" comprises the current quark mass plus the mass equivalence of the energy of the gluon particle field that surrounds the quark, and is significantly more than the rest mass. The current quark masses of the three quarks (uud) in the proton total only around 11 MeV. Up, Down and Strange quarks are considered "light" quarks; the other three are "heavy" quarks. The Bottom quark mass I quote is based on the MS Scheme. The 1S Sceme gives a slightly higher mass of 4.65 ±0.03 GeV.
There is no firm foundation for neutrino masses. The best that can be said is that they have masses that are no more than the quoted figures. Evidence from February 2014 points to the sum of the masses of all three types being be about 0.320 ± 0.081 eV, which means that the maxima shown below are way too high.
Calculation Notes:
In 2010 Professor Christine Davies et al at Glasgow University estimated that the up quark weighs 2.01 +/- 0.14 Mev, and the down quark weighs 4.79 +/- 0.16 MeV. The Higgs appears to have a mass around 125 to 126 GeV as at October 2013.
