摘要:

The non-perturbative aspects of quantum field theory are explored in which

the central ingredients are the symmetry principles, the polology of matrix

elements, and the renormalization that takes account of radiative corrections.

As a generalization of the methods first used in an understanding of the

attributes and behaviour of pions and nucleons, it is to utilize the effctive field

theory approach to study the properties of the axion, which is the corollary

of the strategy to solve the problem of parity and time-reversal violation by

non-perturbative e ects in quantum chromodynamics. In particular, with the

s as well as the u and d quarks regarded as relatively light we derive formula

for the mass of the axion; a rough estimate of the rate for its dominant decay

mode at low energy is also carried out.
