Fundamental pole parameters of the N(1470)
The position and residue of the S-matrix pole of the Delta (1236) have been shown to be unique and independent of the particular resonance formula used, thus resolving a discrepancy among phenomenological fits. Unlike the P/sub 33/ partial wave, the P/sub 11/ resonance is highly inelastic, very broa...

| description | The position and residue of the S-matrix pole of the Delta (1236) have been shown to be unique and independent of the particular resonance formula used, thus resolving a discrepancy among phenomenological fits. Unlike the P/sub 33/ partial wave, the P/sub 11/ resonance is highly inelastic, very broad, and has a large background. This produces huge uncertainties in its mass and width, depending on the parametrization used. It is reported that the position of the N(1470) pole is uniquely determined, 1380-110i MeV, from fits to the CERN phase shifts. (10 refs). |
