Symmetry schemes for elementary particles
Abstract
In this dissertation an attempt has "been made to distinguish
between results "based on a relativistic combination of spin and
SU(3) internal symmetry and one of spin and U(2) internal symmetry, An attempt has also been made to allow spin-dependent
modifications to these theories so that the results are less
vague in that the correct masses of particles appear in the
theories.
To facilitate understanding of this subject the early part
of the thesis is devoted to some aspects of group theory required
in later sections. As a further introductory consideration we
consider the internal group SU(3) and its non-relativistic combination with spin SU(6).
