Casimir能量对轻强子袋模型唯象的影响
Effect of the Casimir energy on the bag model phenomenology of light hadrons
摘要:
在考虑质心修正的袋模型中,研究了轻强子质量和重子磁矩对Casimir能量大小的依赖关系。模型中有七个自由参数。其中六个参数是由某些强子质量的拟合确定的,最后一个参数(卡西米尔能量参数)是由轻重子磁矩的最佳拟合确定的。将预测的磁矩与其它模型的计算结果和实验数据进行了比较。
英文摘要:
The dependence of light hadron masses and baryon magnetic moments on the magnitude of the Casimir energy is examined in the bag model with center-of-mass corrections. There are seven free parameters in the model. Six of them are determined from the fit to the masses of certain hadrons, and the last one (Casimir energy parameter) from the best fit to the magnetic moments of light baryons. The predicted magnetic moments are compared with the results obtained in various other models and with experiment data.
