$\Theta +$: Another Explanation and Prediction

Abstract

Recently the so-called ${\Theta }^{+}$ resonance has been reported first from SPring8\cite{nakano} and many following experiments showed apparent confirmation of the state. Since ${\Theta }^{+}$ exclusively decays into either $K^{+}n$ or $K^{0}p$, it is explained as the predicted pentaquark state which includes $uudd\bar{s}$ quarks. However, one yet has to obtain consistent picture of ${\Theta }^{+}$ and its quantum numbers. We try to explain ${\Theta }^{+}$ in a conventional picture and show that such picture leads to new predictions on kaon and pion system.
