... down (or d) quark. – A u-quark has charge +2/3 – A d-quark has charge –1/3 The neutron consists of just the opposite: two d’s and a u – Hence it has charge 0 The u and d quarks weigh the same, about 1/3 the proton mass – That explains the fact that m(n) = m(p) to about ...

More on the Standard Model
... The color charge holding the quarks together is so strong, you can never pull a free quark out of a proton. The harder you try to pull a quark out of a proton, the more mesons you get! The stream of mesons that marks the path of a quark we call a jet. ...

The LHC Experiment at CERN
... Not the case of unified Electroweak theory until we take into account interaction of particles with Higgs. In vacuum, photon has zero mass and velocity = c. But in glass velocity < c photon has an effective mass! This is the effect of photon interacting with EM field of matter. Higgs is a quantum ...
