Calculation of the pentaquark width by QCD sum rule
Abstract
Description
The pentaquark width is calculated in QCD sum rules. Result for $Γ_Θ$ show, that $Γ_Θ$ can vary in the region less than 1$MeV$. The main conclusion is, that if pentaquark is genuine states then sum rules really predict the narrow width of pentaquark $θ^+$, and the suppression of the width is both parametrical and numerical.
