Magnetic moment of the pentaquark ${\Theta }^{+}(1540)$ with light-cone QCD sum rules

Abstract

In this article, we study the magnetic moment of the pentaquark state ${\Theta }^{+}(1540)$ as diquark-diquark-antiquark ($[ud][ud]\bar{s}$) state in the framework of the light-cone QCD sum rules approach. The numerical results indicate the magnetic moment of the pentaquark state ${\Theta }^{+}(1540)$ is about ${\mu }_{{\Theta }^{+}}=-(0.49\pm 0.06){\mu }_N$.
