Query: The impact of asymmetric neutrino emissions on nucleosynthesis in
  core-collapse supernovae   We investigate the impact of asymmetric neutrino emissions on the explosive
nucleosynthesis in neutrino-driven core-collapse supernovae (CCSNe). We find
that the asymmetric emissions tend to yield larger amounts of proton-rich
ejecta (electron fraction, $Y_e > 0.51$) in the hemisphere of the higher
$\nu_{\rm e}$ emissions, meanwhile neutron-rich matter ($Y_e < 0.49$) are
ejected in the opposite hemisphere of the higher ${\bar \nu}_{\rm e}$
emissions. For larger asymmetric cases with $\ge 30\%$, the neutron-rich ejecta
is abundantly produced, in which there are too much elements heavier than Zn
compared to the solar abundances. This may place an upper limit of the
asymmetric neutrino emissions in CCSNe. The characteristic features are also
observed in elemental distribution; (1) abundances lighter than Ca are
insensitive to the asymmetric neutrino emissions: (2) the production of Zn and
Ge is larger in the neutron-rich ejecta even for smaller asymmetric cases with
$\le 10\%$. We discuss these observational consequences, which may account for
the (anti-)correlations among asymmetries of heavy elements and neutron star
kicks in supernova remnants (SNRs). Future SNR observations of the direct
measurement for the mass and spatial distributions of $\alpha$ elements, Fe, Zn
and Ge will provide us the information on the asymmetric degree of neutrino
emissions.
