One-loop calculations of hyperon polarizabilities under the large N_c consistency condition
Y. Tanushi, S. Saito, M. Uehara
The spin-averaged electromagnetic polarizabilities of the hyperons and are calculated within the one-loop approximation by use of the dispersion theory. The photon and meso…
Spin-Polarizabilities of the Nucleon in Chiral Soliton Model with Dispersion Relation
Y. Tanushi, S. Saito, M. Uehara
We calculate the spin-polarizabilities of the nucleon by means of dispersion relation, where the pion photoproduction amplitude predicted by chiral soliton model is utilized. We co…
Spin-dependent Polarizability of Nucleon with Dispersion Relation in the Skyrme Model
Y. Tanushi, Y. Nakahara, S. Saito +1
We calculate the spin-dependent polarizability of the nucleon in the Skyrme model. The result is compared with that of a heavy baryon chiral perturbation theory(HBChPT), and is sho…
Meson-hyperon couplings in the bound-state approach to the Skyrme model
Y. Kondo, S. Saito, Y. Tanushi +1
Strong pion and kaon couplings to hyperons are given in the bound-state approach to the Skyrme model.
