Abstract

In this work we investigate the consequences of the Jaffe and Wilczek diquark model in the framework of QCD sum rules. An analysis of the O+(1540) as (ud2s state shows that the mass of the pentaquark is compatible with the experimentally measured value. The mass difference between the Θ+ and the pentaquark with the quantum numbers of the nucleon amounts to 70 MeV and is consistent with the interpretation of the N(1440) as a pentaquark.
