Elementary Particles in Physics
www.physics.upenn.eduSix types of quarks have been identified (Table 2). As with the leptons, there is no understanding of the extreme hierarchy of quark masses. For each type of quark there is a corresponding antiquark. Baryons are bound states of three quarks (e.g., proton = uud; neutron = udd), while mesons consist of a quark and an antiquark.

Here we use the word “understand” loosely, in the sense that we know what the Lagrangian is which describes how these forces induce dynamics on matter, and at least in principle we know how to calculate
