研究了超对称性和软破标度对称性和手征对称性的同时非线性实现。为了保证对称的Nambu-Goldstone实现，Goldstino衰变常数被强迫随着显式软标度和手征对称破缺参数的变化而变化。因此，它必然在手征极限中消失，并且超对称和标度对称的同时非线性实现被证明是不一致的。(C)2000年美国物理学会。
Simultaneous nonlinear realizations of supersymmetry and softly broken scale and chiral symmetries are investigated. To guarantee Nambu-Goldstone realizations of the symmetries, the Goldstino decay constant is forced to vary as the explicit soft scale and chiral symmetry breaking parameters. Consequently, it must vanish in the chiral limit and the simultaneous nonlinear realizations of the super and scale symmetries prove inconsistent. (c) 2000 The American Physical Society.
