Exotic baryon states in QCD sum rule
Abstract
Description
It is shown, that the small decay width of $Θ^+ = uudd\bar{s}$ baryon is suppressed by chirality violation. It is shown that $Θ^+$ decay width $Γ$ is proportional to $α^2_s < 0 | \bar{q} q | 0 >^2$, for any pentaquark current without derivatives.
