P. D. Jarvis, S. M. Inglis

摘要:

我们证明了与阿贝尔规范场最小耦合的Duffin-Kemmer-Petiau方程可以看作是物质场内部产生的规范势的矩阵方程。这可以解决作为一个合理的表达方面的电流双线性的物质波函数,连同一个类似的表达的场强张量,从而提供了一个规范不变制定的自相互作用DKP方程。我们推导出这个结果的5个组件的DKP系统,类比狄拉克方程的情况下。为此,我们建立的代数结构的双线性电流的集合,和最小生成集,其中包括两个标量和两个四向量,连同一个单一的二次约束的属性。

英文摘要:

We show that the Duffin-Kemmer-Petiau equation, minimally coupled to an Abelian gauge field, can be regarded as a matrix equation for the gauge potential produced internally from the matter fields. This can be solved as a rational expression in terms of currents bilinear in the matter wavefunction, together with a similar expression for the field strength tensor, thus providing a gauge invariant formulation of the self-interacting DKP equations. We give the derivation of this result for the 5 component DKP system, by analogy with the Dirac equation case. To this end, we establish the algebraic structure of the set of bilinear currents, and the properties of the minimal generating set, which consists of two scalars and two four-vectors, together with a single quadratic constraint.
