Within the framework of the light-cone QCD sum rules method (LCSR’s), the radiative $\Delta \left(1600\right)\to \gamma N$ decay is studied. In particular, the magnetic dipole moment $G_M^1\left(0\right)$ and the electric quadrupole moment $G_E^1\left(0\right)$ are estimated. We also calculate the ratio $R_{EM}=-\frac{G_E^1\left(0\right)}{G_M^1\left(0\right)}$ and the decay rate. The predicted multipole moments and the decay rate strongly agree with the existing experimental results as well as with the other available phenomenological approaches.

光锥 QCD 和规则中的辐射 Δ(1600) → γN 衰减

在光锥 QCD 和规则方法 (LCSR) 的框架内，辐射 $\Delta \left(1600\right)\to \gamma N$衰变进行了研究。特别是磁偶极矩$G_{米}^1\left(0\right)$ 和电四极矩 $G_{乙}^1\left(0\right)$估计。我们还计算了比率${\mathrm{电阻}}_{乙米}=-\frac{G_{乙}^1\left(0\right)}{G_{米}^1\left(0\right)}$和衰减率。预测的多极矩和衰减率与现有的实验结果以及其他可用的现象学方法非常一致。
