Rarita-Schwinger场列式的壳层相容性

On-shell consistency of the Rarita-Schwinger field formulation

H. Krebs, E. Epelbaum, U. -G. Meißner

摘要:

我们证明了,任何双线性耦合的质量自旋3/2场可以带到规范不变的Pascalutsa建议的形式通过一个非线性场的重新定义。给出了相应的场变换的封闭形式,并讨论了其对具有Delta(1232)等压线自由度的手征有效场论的意义.

英文摘要:

We prove that any bilinear coupling of a massive spin-3/2 field can be brought into a gauge invariant form suggested by Pascalutsa by means of a non-linear field redefinition. The corresponding field transformation is given explicitly in a closed form and the implications for chiral effective field theory with explicit Delta (1232) isobar degrees of freedom are discussed.
