Planck Scale Effects on the Majoron
The hypothesis that non-perturbative gravitational effects lead to explicit breaking of global symmetries is considered in the context of Majoron models. We find that the nonvanishing Majoron mass generated by these effects can overclose the universe unless the massive Majoron is unstable. The cosmological mass density constraints can then be satisfied only if V BL < 10 TeV, where V BL is the s...
متن کاملComputability at the Planck Scale
We consider the issue of computability at the most fundamental level of physical reality: the Planck scale. To this aim, we consider the theoretical model of a quantum computer on a non commutative space background, which is a computational model for quantum gravity. In this domain, all computable functions are the laws of physics in their most primordial form, and non computable mathematics fi...
متن کاملHiggs and Super-higgs Effects with Naturally Vanishing Vacuum Energy
We construct N = 1 supergravity models where the gauge symmetry and supersymmetry are both spontaneously broken, with naturally vanishing classical vacuum energy and unsuppressed Goldstino components along gauge non-singlet directions. We discuss some physically interesting situations where such a mechanism could play a role, and identify the breaking of a grand-unified gauge group as the most ...

Boucenna, Edificio de Institutos de Paterna, Instituto de Física Corpuscular – C.S.I.C./ Universitat de València, Apartado 22085, E–46071 València, Spain e-mail: [email protected] There exists a widely known conjecture that gravitational effects violate global symmetries. We study the effect of global-symmetry violating higher-dimension operators induced by Planck-...
متن کاملOn the Structure of Space-Time at the Planck Scale
The set of space-time short-distance structures which can be described through linear operators is limited to a few basic cases. These are continua, lattices and a further short-distance structure which implies an ultraviolet cut-off. Under certain conditions, these cut-off degrees of freedom can reappear as internal degrees of freedom. We review the current status of the classification and pre...
