THE COUPLING OF THE f1(1285) MESON TO THE ISOSCALAR AXIAL CURRENT OF THE NUCLEON
Abstract
The weak decay as well as the strong nucleon coupling constants of the isoscalar axial vector meson f1 (1285) are estimated within the octet quark model. It is shown that the empirical value for the coupling of ss quarkonium to nucleons can be understood by attributing the f1(1285)-nucleon coupling to the a0π N triangle diagram.
