Hyphenation of the scalartensor modelComments: 12 pages, 4 figures
We study the scalartensor model in the presence of nonperturbative background parameters and derive the hypertheoretic model in the presence of nonperturbative background parameters. We find that in the presence of nonperturbative background parameters the model degenerates to the second order model, which is the one that corresponds to the vacuum state of the scalartensor model with the Higgs collapse.

Entanglement entropy of a compact of entangled scalar fields in a $D$dimensional RiemannSennholtz modelComments: 54 pages
We study the entanglement entropy of a compact of $U(1)$ scalar fields in a $D$dimensional RiemannSennholtz model, in the presence of a $D$dimensional Schwarzschild radiation. We consider the entanglement entropy of the compact in the presence of two spatial dimensions in the $D$dimensional RiemannSennholtz model. We find that the entropy of the compact is independent on the spatial dimension of the scalar fields. In the second order model, we find that the entropy of the compact depends on the spatial dimension of the scalar fields.

Primordial Black Hole Scattering at the Early UniverseComments: 15 pages, 2 figures. v2: minor corrections
We use a new approach to study the black hole and therefore the cosmological constant problem at large scales of the universe. We derive a new finitetemperature scaling technique to measure scattering amplitudes of primordial black holes and find that their scattering amplitude is in a class of (1+1) scales, whose amplitudes are defined by the amplitude of the primordial black hole. The results significantly extend the results of previous studies of scattering amplitudes of primordial black holes and show that the scattering amplitude does not significantly increase with the expansion of the universe. It is also shown that the scattering amplitude of primordial black holes is related to the length of time the particles are in the black hole. This point is made by using the example of a black hole as a "switch" in the universe. If a switch is inserted in the universe on the finitetemperature scale, then the black hole is at the same temperature as the universe at large scales. This extended model is probabilistically expected to have a primordial black hole on the earlytime scales.
