Abstract
Different experiments on hadron spectroscopy have long suspected the existence of several cascade states in the region. They are usually labeled under the common name of . As we argue here, there are also theoretical reasons supporting the idea of several resonances. In particular, we propose the existence of three states: one of these states would be part of a spin-parity decuplet and the other two probably would belong to the and octets. We also identify which decay channels are the more appropriate for the detection of each of the previous states.
