Understanding the Nature of through Regge Physics
Cesar Fernandez-Ramirez, Igor V. Danilkin, Vincent Mathieu +1
It appears that there are two resonances with quantum numbers in the energy region near the hyperon. The nature of these states is a topic of current debate.…
Coupled-Channel Model for Scattering in the Resonant Region
C. Fernandez-Ramirez, I. V. Danilkin, D. M. Manley +2
We present a unitary multichannel model for scattering in the resonance region that fulfills unitarity. It has the correct analytical properties for the amplitudes once…
Toward Complete Pion Nucleon Amplitudes
V. Mathieu, I. V. Danilkin, C. Fernández-Ramírez +4
We compare the low-energy partial wave analyses scattering with a high-energy data via finite energy sum rules. We construct a new set of amplitudes by matching the imaginary…
Three-body Final State Interaction in
Peng Guo, Igor V. Danilkin, Diane Schott +3
We present an unitary dispersive model for the decay process based upon the Khuri-Treiman equations which are solved by means of the Pasquier inversion method. The descr…
