Abstract
The quantum field theory built upon the SU(2) Yang-Mills pseudoparticle solution is studied in an O(5) covariant formalism. The gauge ghost and small oscillations of the Yang-Mills field problems are analyzed completely on the O(5) hypersphere, and it is shown that solutions of the various eigenvalue equations may be easily projected back into Euclidean space. Zero-frequency modes in the small oscillations are found, and their interpretation is given within the framework of the O(5,1) conformal group.Keywords
