Calculation of the pentaquark width by QCD sum rule

Abstract

The pentaquark width is calculated in QCD sum rules. Result for ${\Gamma }_{\Theta }$ show, that ${\Gamma }_{\Theta }$ 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 ${\theta }^{+}$, and the suppression of the width is both parametrical and numerical.
