相对论核模型中四流和求和规则的交换子

Commutators of the four-current and sum rules in relativistic nuclear models

H. Kurasawa, T. Suzuki

摘要:

在相对论场论和核模型中,激发强度的线性能量加权和一直存在一个问题:其和值应是正定的,而用激发算符与狄拉克哈密顿量的电流交换子或双交换子进行简单计算时,其和值为零。这一悖论的矛盾是以分析的方式解决的。

英文摘要:

There is a long-standing problem on the linearly energy-weighted sum of the excitation strengths in the relativistic field theory and nuclear models: The sum value should be positively definite, while its naive calculation using the current commutator or the double commutator of the excitation operator with Dirac Hamiltonian yields the value to vanish. This paradoxical contradiction is solved in an analytic way.
