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…
A new approach to axial coupling constants in the QCD sum rule
T. Nishikawa, S. Saito, Y. Kondo
We derive new QCD sum rules for the axial coupling constants by considering two-point correlation functions of the axial-vector currents in a one nucleon state. The QCD sum rules t…
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…
Electric Polarizabilities of Neutral Baryons in the QCD Sum Rule
T. Nishikawa, S. Saito, Y. Kondo
We investigate the electric polarizabilities of neutral baryons using the method of QCD sum rules. The diagrams in the operator product expansion are taken into account up to dimen…
Do really the seagull terms survive for the electric polarizability of the nucleon
S. Saito, M. Uehara
The seagull terms for the electric polarizability of the nucleon are shown to vanish, if one introduces fluctuations around the Skyrmion, and the origin of the eletric polarizabili…
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.
