Duffin-Kemmer-Petiau方程与Klein-Gordon方程和Proca方程的等价性

Corroborating the equivalence between the Duffin-Kemmer-Petiau and the Klein-Gordon and Proca equations

L. B. Castro, A. S. de Castro

摘要:

结果表明,具有电磁耦合的Duffin-Kemmer-Petiau理论的哈密顿版本在电流处产生源项。它还表明,这样的源项消失的情况下,如果使用正确的物理形式的Duffin-Kemmer-Petiau字段,无论选择代表的Duffin-Kemmer-Petiau矩阵。这一结果被用来修正Duffin-Kemmer-Petiau理论中电磁耦合的模糊性。此外,还讨论了Duffin-Kemmer-Petiau理论中关于厄米性的一些误解。

英文摘要:

It is shown that the Hamiltonian version of the Duffin-Kemmer-Petiau theory with electromagnetic coupling brings about a source term at the current. It is also shown that such a source term disappears from the scenario if one uses the correct physical form for the Duffin-Kemmer-Petiau field, regardless the choice for representing the Duffin-Kemmer-Petiau matrices. This result is used to fix the ambiguity in the electromagnetic coupling in the Duffin-Kemmer-Petiau theory. Moreover, some widespread misconceptions about the Hermiticity in the Duffin-Kemmer-Petiau theory are discussed.
