A Unitarized Chiral Approach to f0(980) and a0(980) States and Nature of Light Scalar Resonances

M. Uehara

We show that the f_0(980) and a_0(980) states appearing in scattering and production processes can be described quite well by the two-channel Oller-Oset-Peláez (OOP) version of uni…

Large Nc Behavior of Light Scalar Meson Nonet Revisited

M. Uehara

We study whether light scalar meson nonet can survive in large values of Nc through observing how scattering amplitudes behave as Nc increases from 3 within a unitarized chiral app…

Can Low Mass Scalar Meson Nonet Survive in Large N_c Limit ?

Masayuki Uehara

We study, within an approximate Inverse Amplitude Method to unitarize Chiral Perturbation Theory, whether low mass scalar mesons can survive in large N_c regime, and show that vect…

Final State Interactions in Kaon Decays Revisited

Masayuki Uehara

We examine effects of final state interactions (FSI) in kaon decays using a new scheme without the Omnes function, and show that while Delta I=1/2 rule is impossible to be explaine…

Scalar Dipion States Produced in Heavy Quarkonium Decays and the Final State Interaction

M. Uehara

We study phenomenologically the invariant mass spectra of scalar dipion states produced in cascade decays of excited and , and decays into light vector meson. Dipion p…

The f_0(980) and a_0(980) Productions in Two-Photon Collisions and Radiative phi Meson Decays

M. Uehara

We study how the scalar f_0(980) and a_0(980) states are produced in the two-photon collisions and radiative decays of the phi meson through unitarized Born amplitudes with the cha…
