pdg.lbl.gov2. Quarks and leptons are numbered consecutively starting from 1 and 11 respectively; to do this they are first ordered by family and within families by weak isospin. 3. In composite quark systems (diquarks, mesons, and baryons) nq1−3 are quark numbers used to specify the quark content, while the rightmost digit nJ =2J +1 gives the system ...

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.
An Introduction to String Theory
math.berkeley.edubinds quarks into protons and neutrons. We, that is most physicists, believe that we understand all of these forces except for gravity. 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
