What Can we Learn about $\Theta$ Baryon from Unified Picture for Hadron Spectra

Abstract

An analysis of the recent results from several experimental groups reported observation of a new $\Theta$ baryon has been presented from a view point of the unified picture for hadron spectra developed early \cite{12}. It is shown that, in fact, two different $\Theta$ baryons have been discovered. We have also established that both $\Theta$ baryons are excellently incorporated in the unified picture for hadron spectra. It is argued that the presented experimental material revealed an existence of the positive srangeness $\Theta$ partners for the observed $\Lambda$ and $\Sigma$ states with negative strangeness as we predicted.
