Query: Supernova Neutrino Detection in Borexino   We calculated the expected neutrino signal in Borexino from a typical Type II
supernova at a distance of 10 kpc. A burst of around 110 events would appear in
Borexino within a time interval of about 10 s. Most of these events would come
from the reaction channel $\bar{\nu}_e+p\to e^++n$, while about 30 events would
be induced by the interaction of the supernova neutrino flux on $^{12}$C in the
liquid scintillator. Borexino can clearly distinguish between the
neutral-current excitations $^{12}{C}(\nu,\nu')^{12}{C}^*$(15.11 MeV) and the
charged-current reactions $^{12}{C}(\nu_e,e^-)^{12}{N}$ and
$^{12}{C}(\bar{\nu}_e,e^+)^{12}{B}$, via their distinctive event signatures.
The ratio of the charged-current to neutral-current neutrino event rates and
their time profiles with respect to each other can provide a handle on
supernova and non-standard neutrino physics (mass and flavor oscillations).
