Query: Double Beta Decay Constraints on Neutrino Masses and Mixing; Reanalysis
  with KamLAND Data   In the light of KamLAND data just released, we reanalyze and update the
constraints on neutrino masses and mixing parameters, the most general ones
that can be derived in three-flavor mixing scheme of neutrinos with use of the
bounds imposed by neutrinoless double beta decay search and reactor
experiments. We point out that with KamLAND data and assuming Majorana
neutrinos one can derive, for the first time, an upper bound on neutrino
contribution to the cosmological \Omega parameter, \Omega_{\nu} \leq 0.070
h^{-2}, by using the current upper bound on mass parameters obtained by
Heidelberg-Moscow group, < m >_{\beta \beta} < 0.35 eV (90 % CL). If the bound
is tighten to < m >_{\beta \beta} < 0.1 eV by future experiments, it would lead
to a far severer bound \Omega_{\nu} \lsim 0.01 h^{-2}.
