Mildly mixed coupled models vs. WMAP7 data

TL;DR

This paper evaluates mildly mixed coupled dark energy models with massive neutrinos against WMAP7 data, showing they slightly outperform LCDM and discussing implications for neutrino mass detection experiments.

Contribution

It provides new likelihood tests of these models using recent cosmological data, highlighting their potential advantages over LCDM.

Findings

Mildly mixed coupled models slightly better fit WMAP7 data than LCDM.

Neutrino mass detection impacts the physics of dark energy models.

Models are consistent with data at about 2 sigma confidence level.

Abstract

Mildly mixed coupled models include massive neutrinos and CDM--DE coupling. We present new tests of their likelihood vs. recent data including WMAP7, confirming it to exceed LCDM, although at ~2\sigma's. We then show the impact on the physics of the dark components of neutrino mass detection in tritium beta decay or neutrinoless double beta decay experiments.
