Testing Predictions of the Quantum Landscape Multiverse 3: The Hilltop Inflationary Potential

TL;DR

This paper tests the predictions of the quantum landscape multiverse theory against Planck data for Hilltop inflation models, finding that multiverse corrections are statistically indistinguishable from standard inflation and consistent with observed anomalies.

Contribution

It introduces constraints on the SUSY-breaking scale within Hilltop inflation models considering multiverse quantum corrections, aligning predictions with Planck observations.

Findings

Multiverse corrections are statistically indistinguishable from standard inflation.

Predicted anomalies are consistent with Planck data.

Certain models resolve tensions with Hubble and lensing measurements.

Abstract

Here we test the predictions of the theory of the origin of the universe from the landscape multiverse, against the 2015 Planck data, for the case of the Hilltop class of inflationary models, for $p=4$ and $p=6$. By considering the quantum entanglement correction of the multiverse, we can place just a lower limit on the local 'SUSY-breaking' scale, respectively $b>8.7\times10^6 GeV$ at $95 \%$ c.l. and $b>1.3\times10^8 GeV$ at $95 \%$ c.l. from Planck TT+lowP, so the case with multiverse correction is statistically indistinguishable from the case with an unmodified inflation. We find that the series of anomalies predicted by the quantum landscape multiverse for the allowed range of $b$, is consistent with Planck's tests of the anomalies. In addition, the friction between the two cosmological probes of the Hubble parameter and with the weak lensing experiments goes away for a particular subset, the $p=6$ case of Hilltop models.
