Goldstone ghost. Tensor ghost Definition of a
 model in CompHEP Faddeev-Popov
 ghost and anti-ghost Contents

Goldstone ghost.

It is generated for any massive gauge vector particles. The name of this field is constructed by means of suffix 'f'. For example, W+.f, W-.f are the W-boson Goldstone ghosts.

This ghost is scalar, commutative, and satisfies the same conjugation rule as the prototype particle. For example, $(W+.f)^+= W-.f$. The nonzero propagators for these fields are:


\begin{displaymath}T[\mbox{A+.f}(p_1), \; A.f(p_2)] = ScPr(p_1,p_2,M),\end{displaymath}

where $M$ is a mass of the prototype particle.
