Magnetic moment of the pentaquark Θ(1540) with light-cone QCD sum rules

In this article, we study the magnetic moment of the pentaquark state Θ+(1540) as diquark-diquark-antiquark ([ud][ud]s̄) state in the framework of the light-cone QCD sum rules approach. The numerical results indicate the magnetic moment of the pentaquark state Θ+(1540) is about μΘ+ = −(0.49± 0.06)μN . PACS : 12.38.Aw, 12.38.Lg, 12.39.Ba, 12.39.-x
