Pentaquark from QCD sum rules: consequences of the diquark approach
Markus Eidemuller
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 Theta^+(1540) as (ud)^2\bar{s} state shows…

Pentaquark and diquark-diquark clustering: a QCD sum rule approach
Markus Eidemuller
In this work we study the Theta(1540) in the framework of QCD sum rules based on (ud)^2\bar{s} diquark clustering as suggested by Jaffe and Wilczek. Within errors, the mass of the…
