| dc.description | In this article, we study the magnetic moment of the pentaquark $ Θ^+(1540)$ as (scalar)diquark-(pseudoscalar)diquark-antiquark state with the QCD sum rules approach in the external electromagnetic field. Due to the special structure of the interpolating current, only the electromagnetic interactions of the $s$ quark with the external field have contributions to the magnetic moment with tensor structure $\{σ_{μν} {\hat p} +{\hat p}σ_{μν}\}$. The numerical results indicate the magnetic moment of the pentaquark state $ Θ^+(1540)$ is about $μ_{Θ^+}=(0.16\pm0.03)μ_N$. | |
