不定度量场论中的Wick幂级数

Wick Power Series in Indefinite Metric Field Theories

A. G. Smirnov, M. A. Soloviev

摘要:

考虑了红外奇异自由场Wick幂级数算子实现的解析方面。利用两点关联函数及其Hilbert优变量在x-空间中的全纯性质,我们以一种与模型无关的一般方法解决了寻找一个能使Wick级数收敛的适当检验函数空间的问题.大量的注意力被支付到适当的制定的频谱条件的情况下,合适的测试功能是整个分析的动量空间。

英文摘要:

The analytic aspects of the operator realization of Wick power series of infrared singular free fields are considered. Taking advantage of the holomorphy properties of the two-point correlation function and its Hilbert majorant in x-space, we solve in a general and model independent way the problem of finding the adequate test function space on which a given Wick series is convergent. Substantial attention is paid to the proper formulation of the spectral condition in case the suitable test functions are entire analytic in momentum space.
