Menotti and Pelissetto [166] performed a one-loop calculation and found that the
Slavnov-Taylor identity can be satisfied for a particular choice
of
N,
(momentum expansion coefficients of
f), and of the cosmological constant
. The solution still depends on a real parameter
(related to a residual non-invariance under rotations). This
makes it difficult to draw any immediate conclusions on the
structure of the full, non-perturbative measure.
