粲介子的重夸克有效理论

Heavy quark effective theory for charmed mesons

S. Singh, M. Batra, A. Upadhyay

摘要:

在重夸克有效理论和手征微扰理论的框架下,研究了重粲介子的质量和分裂。利用质量公式对低激发粲介子态进行了全面的分析,着重讨论了质量劈裂和自旋劈裂随各种对称性守恒和对称性破缺参数的变化。

英文摘要:

Within the framework of heavy quark effective theory and chiral perturbation theory, masses and splittings of heavy charm mesons are studied. A mass formula is used for comprehensive analysis of low lying charm meson states.The variation of mass splittings and spin splittings with respect to various symmetry conserving and symmetry breaking parameters have also been focussed.
