Dark matter and dark energy via nonperturbative (flavor) vacua

Abstract

A non-perturbative field theoretical approach to flavour physics (Blasone-Vitiello formalism) has been shown to imply a highly non-trivial vacuum state. Although still far from representing a satisfactory framework for a coherent and complete characterization of flavour states, in recent years the formalism has received attention for its possible implications at cosmological scales. In a previous work, we implemented the approach on a simple supersymmetric model (free Wess-Zumino), with flavour mixing, which was regarded as a model for free neutrinos and sneutrinos. The resulting effective vacuum (called flavour vacuum) was found to be characterized by a strong SUSY breaking. In this paper we explore the phenomenology of the model and we argue that the flavour vacuum is a consistent source for both Dark Energy (thanks to the bosonic sector of the model) and Dark Matter (via the fermionic one). Quite remarkably, besides the parameters connected with neutrino physics, in this model no other parameters have been introduced, possibly leading to a predictive theory of Dark Energy/Matter. Despite its oversimplification, such a toy model already seems capable to shed some light on the observed energy hierarchy between neutrino physics, Dark Energy and Dark Matter. Furthermore, we move a step forth in the construction of a more realistic theory, by presenting a novel approach for calculating relevant quantities and hence extending some results to interactive theories, in a completely non-perturbative way.PACS numbers: 14.60.

Dark Matter and Dark Energy Induced by Condensates

“…For such systems, starting from the results of our previous works [44,45,49], and from the ones presented in Refs. [55,59], obtained in a supersymmetric context, one shows that the flavor neutrino vacuum can give a contribution to the dark matter with a value compatible with its estimated upper bound, while, the quark condensate, because of the quark confinement inside the hadrons should not interact gravitationally. Moreover, one shows that the condensate of mixed boson [42,43], as axions and axion like particles (ALPs) in their interaction with photons, and of superpartners of mixed neutrinos, can contribute to the dark energy with the state equation of the cosmological constant.…”
