In particular, we discuss the possibilities of probing the mixing angle $\theta_{13}$ and determining the sign of $\Delta m^2_{32}$ from the total charged current(CC) event rates on the proton and $^{12}{C}$ target, as well as from the CC spectra. We discuss the chances of probing the earth matter effect induced modulations from the observation of CC spectra in the different CC reactions in KamLAND and find the volume required to get a statistically significant signature of the earth matter effect in different energy bins. We also calculate the event rates expected in the neutral current (NC) reactions on Carbon and free proton and investigate if the charged current to neutral current ratios, which are free of the absolute luminosity uncertainty in the supernova neutrino fluxes, can be useful in probing the oscillation parameters. en_US dc.format.extent 702674 bytes en_US dc.format.mimetype application/pdf en_US dc.language.iso en_US en_US dc.publisher SISSA en_US dc.relation.ispartofseries SISSA;114/2003/EP en_US dc.title Prospects of probing $\theta_{13}$ and neutrino mass hierarchy by Supernova Neutrinos in KamLAND en_US dc.type Preprint en_US dc.contributor.department Elementary Particle Theory en_US dc.contributor.area Physics en_US
