Description

There is a strong conflict between the huge value of vacuum energy according to theoretical estimates and the observed upper bound of its value. We propose a mechanism of the vacuum energy adjustment down to the existing observational limits via an interaction of the massless scalar field with the curvature scalar. An uncompensated remnant could possibly be identified with the observed magnitude of the cosmological dark energy.
