Cosmological avatars of the landscape. I. Bracketing the supersymmetry breaking scale

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 wavefunction 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 −10 M P ≤ M SUSY ≤ 10 −8 M P for GUT scale inflation. The lower bound is at least five orders of magnitude larger than the expected value of this parameter and can be tested by LHC physics.

Birth of the Universe From the Multiverse

“…The result is an overall suppression of the amplitude of perturbations, σ 8 , and a hole which in the sky show up as voids. But, considering that at present the strength of nonlocal entanglement is very small, then without resorting to the mathematical expression for Φ in [12,13], it can still be understood why the maximum modification, i.e. voids, will be found at very large scales, at the 'edges' of the universe, where the entanglement strength is relatively larger and physics is nearly linear.…”

“…Therefore the collection of all string vacua solutions that comprise the landscape, is an ensemble of possible universes [4,5,1,2,12,13]. We can think of the landscape of string theory as the energy profile V (φ) of some string moduli field φ, which plays the role of a collective coordinate.…”

“…When tracing out the effect of nonlocal entanglement on our universe, the energy of the initial waveapacket of our universe gets shifted and that shift produces the observable modification on the background potential of the universe. This modification to the primordial spectrum of perturbation and the Newtonian gravitational potential Φ, derived in [12,13], which is superimposed to the standard inflationary potential Φ 0 , when evolved to present times carries all the observational imprints that can be observed in LSS and CMB, discussed in [12,13].…”

“…This new term added to the WdW hamiltonian H 0 , represents the backreaction of the 'bath' onto the 'system ' [18,19]. With the inclusion of the backreaction term, the WdW equation becomes a 'Master' equation [4,12,13]…”

“…These two reasons provide a whole series of imprints on the large scale structure (LSS) and cosmic microwave anisotropies (CMB) in the universe, derived in [12,13].…”
