Search for narrow resonances inπpelastic scattering from the EPECUR experiment

et al. 2016

The analysis of high-precision π ± p → π ± p cross section data from the EPECUR Collaboration based on the multichannel K-matrix approach is presented. The sharp structures seen in these data are studied in terms of both opening thresholds and new resonance contributions. Some prominent features are found to be due to the opening KΣ channel. However, a complete description of the data is improved with the addition of two narrow resonant structures at W ∼ 1.686 and W ∼ 1.720 GeV. These structures are interpreted as manifestations of S11 and P11 resonances. The underlying nature of the observed phenomena is discussed.
