Abstract

It is shown that if the a[sub 0](980) boson is the scalar chiral partner of a π meson, its contribution to the transition η → πγγ has a value comparable to that originated by vector meson exchange. Together, these two mechanisms give the decay probability consistent with the experimental observation. [ABSTRACT FROM AUTHOR]
