Query: The impact of neutrino masses on the determination of dark energy
  properties   Recently, the Heidelberg-Moscow double beta decay experiment has claimed a
detection for a neutrino mass with high significance. Here we consider the
impact of this measurement on the determination of the dark energy equation of
state. By combining the Heidelberg-Moscow result with the WMAP 3-years data and
other cosmological datasets we constrain the equation of state to -1.67< w
<-1.05 at 95% c.l., ruling out a cosmological constant at more than 95% c.l..
Interestingly enough, coupled neutrino-dark energy models may be consistent
with such equation of state. While future data are certainly needed for a
confirmation of the controversial Heildelberg-Moscow claim, our result shows
that future laboratory searches for neutrino masses may play a crucial role in
the determination of the dark energy properties.
