标题： Bosonic color-flavor transformation for the special unitary group

摘要： 我们将Zirnbauer在玻色子部分的色彩-味变换扩展到色彩群SU(N_c)。 由于味群U(N_b, N_b)是非紧致的，通过原始色彩-味变换推导出的代数方法仅在2N_b \le N_c时给出有用的结果。 使用特征展开方法，我们在扩展范围N_b \le N_c内得到了变换的不同形式。 该结果也可用于色彩群 U(N_c)。 可以应用该变换的积分与最近提出的玻色子诱导格点规范理论相关。 显示英文摘要

摘要： We extend Zirnbauer's color-flavor transformation in the bosonic sector to the color group SU(N_c). Because the flavor group U(N_b, N_b) is non-compact, the algebraic method by which the original color-flavor transformation was derived leads to a useful result only for 2N_b \le N_c. Using the character expansion method, we obtain a different form of the transformation in the extended range N_b \le N_c. This result can also be used for the color group U(N_c). The integrals to which the transformation can be applied are of relevance for the recently proposed boson-induced lattice gauge theory.
