Abstract
We investigate the effects of quantum entanglement between our horizon patch and others due to the tracing out of long wavelength modes in the wave function of the Universe as defined on a particular model of the landscape. In this, the first of two papers devoted to this topic, we find that the SUSY breaking scale is bounded both above and below: ${10}^{\ensuremath{-}10}{M}_{\mathrm{P}}\ensuremath{\le}{M}_{\mathrm{SUSY}}\ensuremath{\le}{10}^{\ensuremath{-}8}{M}_{\mathrm{P}}$ for grand unified theory (GUT) scale inflation. Bounds on the SUSY breaking parameter depend on the scale of inflation. If inflation occurred at GUT energies, the lower bound on $b$ is at least 5 orders of magnitude larger than the expected value of this parameter, soon to be tested by LHC.
