Constraining the chirally motivated πΣ−K¯N models with the πΣ photoproduction mass spectra
Original language description
The paper presents a first time attempt on a combined fit of the K(-)p low-energy data and the pi Sigma photoproduction mass spectra, performed without fixing the meson-baryon rescattering amplitudes to a specific pi Sigma - (k) over barN coupled channels model obtained from fitting exclusively the K(-)p data. The formalism adopted to describe the photoproduction process is based on chiral perturbation theory and employs a limited number of free parameters. The achieved description of the photoproduction mass distributions is not quite satisfactory, leaving a room for improving the photo-kernel construction. Although the presented models tend to constrain the positions of the Lambda(1405) poles it is difficult to draw any conclusions before accomplishing better data reproduction.
