New Concept of First Quantization
T. Fujita, S. Kanemaki, S. Oshima
We derive a Lagrangian density of Dirac field by employing the local gauge invariance and the Maxwell equation as the fundamental principle. The only assumption made here is that t…

Problems of Real Scalar Klein-Gordon Field
Sachiko Oshima, Seiji Kanemaki, Takehisa Fujita
We examine the negative energy solution in Klein-Gordon equation in terms of the number of field components. A scalar field has only one component, and there is no freedom left for…

Gauge non-invariance of quark-quark interactions
T. Fujita, S. Kanemaki, S. Oshima
We discuss the gauge invariance of quark-quark potential in QCD in the perturbative treatment, and show that the gauge dependence of the quark-gluon interaction cannot be eliminate…
