Can we predict Λ for the Non-SUSY sector of the Landscape?

Mersini-Houghton, Laura

Original · EN

We propose a new selection criteria for predicting the most probable wavefunction of the universe that propagates on the string landscape background, by studying its dynamics from a quantum cosmology view. Previously we applied this proposal to the SUSY sector of the landscape. In this work the dynamic selection criterion is applied to the investigation of the non-SUSY sector.In the absence of detailed information about its structure, it is assumed that this sector has a stochastic distribution of vacua energies.The calculation of a distribution probability for the cosmological constants Λeff, obtained from the density of states ρ, indicates that the most probable wavefunction is peaked around universes with zero Λeff. In contrast to the extended wavefunction solutions found for the SUSY sector with N-vacua and peaked around Λeff≃ 1/N², wavefunctions residing on the non-SUSY sector exhibit Anderson localization.Although minisuperspace is a limited approach it presently provides a dynamical quantum selection rule for the most probable vacua solution from the landscape.
