Abstract:
We study the impact of neutrino oscillations
on the supernova neutrino signal
in the Large Volume Detector (LVD).
The number of expected events for a galactic supernova ($D=10$ Kpc)
is calculated, assuming neutrino masses and mixing that
explain solar and atmospheric neutrino results.
The possibility to detect neutrinos in different channels
makes LVD sensitive to different
scenarios for $\nu$ properties, such as
normal or inverted $\nu$ mass hierarchy, and/or
adiabatic or non adiabatic MSW resonances associated to $U_{\rm e3}.$
Of particular importance are the charged current (c.c.) reactions on
$^{12}{\rm C}$: oscillations increase by almost one order of
magnitude the number of events expected from this channel.
%We study the implications on the supernova neutrino signal in liquid
%scintillator detectors due to the discovery of neutrino oscillations in
%atmospheric and solar neutrinos.\\
%The combined detection of neutrinos through different interaction channels
%can help to distinguish between direct or inverse mass hierarchy and between
%adiabatic or non adiabatic conditions at the resonance
%($U_{\rm e3}^2\ll\gg 5\cdot 10^{-4}$).
