非奇异双重子ΔΔ结合能计算

The Calculation of Binding Energy for Deltaron

在推广的带矢量场的手征SU(3)夸克模型下,计算了非奇异的双重子ΔΔ结合能,我们分别考虑了分波耦合和隐色道(CC)耦合对ΔΔ双重子结合能的影响.结果表明,推广的带矢量场的手征SU(3)夸克模型和不带矢量场的手征SU(3)夸克模型给出的定性结果是一样的,即ΔΔ双重子的质量比两个Δ的质量小,但是比ΔNπ质量大.

The binding energy of the AAdibaryon is calculated by the extended chiral SU（3） quark model with vector field. The ground state energy of the AAdibaryon is calculated, considering both the AA and CC （hidden color）channels. We compare the results in the chiral SU（3）quark model and in the extended chiral SU（3） quark model.
