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

Abstract

In this article, we study the magnetic moment of the pentaquark state ${\Theta }^{+}(1540)$ with the QCD sum rules approach in the external electromagnetic field. The numerical results indicate the magnetic moment of the pentaquark state ${\Theta }^{+}(1540)$ is about ${\mu }_{{\Theta }^{+}}=(0.24\pm 0.02){\mu }_N$.
