Algabraic Properties of Electromagnetic and Weak Currents and their Representation on Hadron States
- SLAC National Accelerator Laboratory (SLAC), Menlo Park, CA (United States)
For almost a decade quark have been used as the basis of a successful description of hadron spectroscopy. As originally introduced by Gell-Mann and Zweig, meson and baryon states are to be constructed from “constituent quark” building blocks as quark-antiquark and three quark states, respectively. With internal angular momentum between the quarks, a simple nonrelativistic prescription for building the hadron states gives both the SU and spin-parity quantum numbers to be expected. Particularly for baryons, where the physical states which exist are best determined, such a scheme is very successful. While there are a number of meson states which are expected in such a quark model but have yet to be found, the relevant experiments are sufficiently difficult that these states could well exist and not have been observed as yet.
