dc.description.abstract | We study the Lambda(1520)D-03 in a chiral coupled channel approach. This resonance appears to be dynamically generated from the interaction of the decuplet of baryons and the octet of mesons in s wave, and its treatment is improved here with the phenomenological inclusion of the KN and pi Sigma channels in d wave. Since the most important building block in Lambda(1520) is the pi Sigma(*)(1385)P-13 channel, we study the K(-)p ->pi Sigma(*)(1385)(pi(0)Lambda) reaction in the region of Lambda(1520) and above, and compare the results with recent experimental data. With the coupling of Lambda(1520) to the pi Sigma(*) channel predicted by the theory, we find a cross section in good agreement with the data. There is also agreement for the invariant mass distributions which show a neat peak for Sigma(*)(1385) in the (pi(0)Lambda) spectrum. Predictions are made of a strong Lambda(1520) resonant peak of the cross section, as a function of the K- momentum, in the region below the measured data, which, if confirmed experimentally, would give stronger support to the idea of Lambda(1520) as a dynamically generated resonance. | |
