DECAY PROBABILITY RATIO OF PENTAQUARK Θ<sup>+</sup> STATE
DECAY PROBABILITY RATIO OF PENTAQUARK Θ<sup>+</sup> STATE
The pentaquark state of $Θ^{+}(uudd\bar{s})$ has been observed to decay with two decay modes: $Θ^+\to n K^+$ and $Θ^+ \to p K^0$. The decay probability ratio of the two decay modes is studied with general symmetry consideration of isospin, spin, and parity. We arrive at a result of the ratio …
