Query: Degenerate spectrum in the neutrino mass anarchy with Wishart matrices
  and implications for $0\nu\beta\beta$ and $\delta_{\rm CP}$   We show that a degenerate neutrino mass spectrum can be realized in the
neutrino mass anarchy hypothesis, if the neutrino Yukawa and right-handed
neutrino mass matrices are given by the Wishart matrix, i.e. products of $N
\times 3$ rectangular random matrices, whose eigenvalue distribution tends to
degenerate for large $N$. The mixing angle and CP phase distributions are
determined by either the Haar measure of U(3) or that of SO(3). We study how
large $N$ is allowed to be without tension with the observed neutrino mass
squared differences, and find that the predicted value of $m_{ee}$ can be
within the reach of future $0\nu\beta\beta$ experiments especially for $N$ on
the high side of the allowed range.
