Calculation of the pentaquark width by QCD sum rule
Abstract
The pentaquark width is calculated in QCD sum rules. Result for show, that can vary in the region less than 1MeV. 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.
