In the presence of non-perturbative effects, dynamical coherence in non-perturbative gravity is often discussed. We focus on the case of non-perturbative gravity with the potential term $\alpha$ containing the scalar components of Einstein gravity. We find that in the presence of a scalar field, the coherence is a logarithmic function of the scalar field energy and the curvature. The coherence then evolves in the background of a massless scalar component. We investigate the coherence function of the scalar component of Einstein gravity and find that the coherence is a logarithmic function of the scalar component of the scalar field. We show that it depends on a parameter which corresponds to the scalar component of Einstein gravity in the presence of a massless scalar component.

Adding the inverse gravitational constant to the Higgs mechanism

M. Karras, S. W. Lobo, V. S. L. M. Magan

Comments: 8 pages, 12 figures

In the context of the Higgs mechanism, a direct approach to the effective potential of the Higgs field is introduced by a simple generalisation of the previous approach of the McArthur-Higgs mechanism. We also consider the expansion and contraction of the effective potential, and determine the Higgs-charge effective action at the energy scale of the Higgs field. We find that the inverse gravitational constant (IGC) of the Higgs field is determined by the expansion and contraction of the Higgs field in the presence of the inverse gravitational constant.
