Abstract
In this lecture we shall confine ourselves to the conventional charm model of weak interactions as proposed [1] by Glashow, Iliopoulos and Maiani (GIM):
-
a)
Hadronic states are assumed to be built from four quarks (u,d,s,c) where (u,d,s) are the Gell-Mann-Zweig quarks and c carries the charm quantum number C = + 1. All hadronic states currently in the Particle Data tables have C = 0.
Lecture given at XV. Internationale Universitatswochen fur Kernphysik,Schladming,Austria,February 16–27,1976.

Tuan, Phys. Rev. Letters 35, 702 (1975); A. De Rujula, H. Georgi and S.L. Glashow, “Vector model of weak interactions”, Harvard preprint (1975). The primary motivation for introducing new quarks with right-handed couplings is that one can construct a theory which is parity conserving in the limit of quark mass degeneracy. Parity violation arises spontaneously through the quark mass matrix generated by the Higgs coupling. The essential prediction of these theories is that the hadronic neutral current is parity conserving.
