Heavy quarks and new particles

Some aspects of particles containing c, b, and heavier quarks are reviewed. It is shown how these particles can provide tests of the short‐range nature of the strong interactions, and how elementary quantum mechanics can reveal the color and charge of the constituents and the number of states below flavor threshold. Some new results are presented on the inverse problem for confining potentials. Properties of flavored hadrons (masses and lifetimes), of gluonic bound states, and of particles containing very heavy objects are also discussed.
