Neutrino Mass Bounds from $0νββ$ Decays and Large Scale Structures Available to Purchase

we investigate the way how the total mass sum of neutrinos can be constrained from the neutrinoless double beta decay and cosmological probes with cosmic microwave background (WMAP 3‐year results), large scale structures including 2dFGRS and SDSS data sets. First we discuss, in brief, on the current status of neutrino mass bounds from neutrino beta decays and cosmic constrain within the flat $ΛCMD$ model. In addition, we explore the interacting neutrino dark‐energy model, where the evolution of neutrino masses is determined by quintessence scalar filed, which is responsable for cosmic acceleration today. Assuming the flatness of the universe, the constraint we can derive from the current observation is $Σmν<0.87 eV$ at the 95% confidence level, which is consistent with $Σmν<0.68 eV$ in the flat $ΛCDM$ model.
