Abstract

Zero temperature properties of an (axial-) vector meson extended linear sigma\nmodel are discussed, concerning on the possible different realizations of the\naxial anomaly term. The different anomaly terms are compared with each other on\nthe basis of a chi² minimalization process. It is found that there is no\nessential difference among the different realizations. This means that any of\nthem can be equally used from phenomenological point of view.\n
