Testing Predictions of the Quantum Landscape Multiverse 1: The Starobinsky Inflationary Potential

TL;DR

This paper tests the landscape multiverse theory's predictions against Planck data for the Starobinsky inflation model, constraining the SUSY breaking scale and linking it to observed anomalies in the CMB.

Contribution

It provides the first observational constraints on the multiverse landscape theory using Planck data, focusing on quantum entanglement effects in the Starobinsky inflation model.

Findings

Lower limit on SUSY breaking scale: b > 1.2×10^7 GeV at 95% confidence level.

The constraints are consistent with the multiverse explaining certain CMB anomalies.

Supports the viability of the landscape multiverse model with quantum entanglement corrections.

Abstract

The 2015 Planck data release has placed tight constraints on the allowed class of inflationary models. The current data favors concave downwards inflationary potentials while offering interesting hints on possible deviations from the standard picture of CMB perturbations. We here test the predictions of the theory of the origin of the universe from the landscape multiverse, against the most recent Planck data, for the case of concave downwards inflationary potentials, such as the Starobinsky model of inflation. By considering the quantum entanglement correction of the multiverse, we can place a lower limit on the local 'SUSY breaking' scale $b>1.2\times10^7 GeV$ at $95 \%$ c.l. from Planck TT+lowTEB. We find that this limit is consistent with the range for $b$ that allows the landscape multiverse to explain a serie of anomalies present in the current data.
