Wightman-Function Approach to the Relativistic Complex-Ghost Field Theory
Noboru Nakanishi
Abstract
The relativistic complex-ghost field theory is covariantly formulated in terms of Wightman functions. The Fourier transform of the 2-point Wightman function of a complex-ghost pair is explicitly calculated, and its spontaneous breakdown of Lorentz invariance is compared with that of the corresponding Feynman integral.
