13 Jul 2000 | | Journal: | Prog.Theor.Phys. 106 (2001) 823-834 | | Subject: | hep-ph | | Abstract: | Double meson production of the eta and pion at the threshold region is investigated in order to determine chiral property of the nucleon. The eta can be used as a probe for the negative parity nucleon $N^* equiv N^*(1535)$ produced in the intermediate state. The coupling of the low energy pion in the final state is then used to extract the sign of the Yukawa coupling, $gpRR$, which distinguishes the two realizations of chiral symmetry, either naive or mirror, for the nucleon. | | Source: | arXiv, hep-ph/0007127 | | Services: | Forum | Review | PDF | Favorites | |
