Study of the effect of neutrino oscillation on the supernova neutrino signal with the LVD detector

We present an update of our previous study [Nucl. Phys. B Proc. Suppl. 110 (2002) 410-413] on how ν oscillations affect the signal from a supernova core collapse observed in the LVD detector at LNGS. In this paper we use a recent, more precise determination of the cross section [A. Strumia and F. Vi...

Zusammenfassung:We present an update of our previous study [Nucl. Phys. B Proc. Suppl. 110 (2002) 410-413] on how ν oscillations affect the signal from a supernova core collapse observed in the LVD detector at LNGS. In this paper we use a recent, more precise determination of the cross section [A. Strumia and F. Vissani, astro-ph/0208035] to calculate the expected number of inverse beta decay events; we introduce in the simulation also the ν-Fe interactions; we include the Earth matter effects; and finally we study also the inverted mass hierarchy case.
