Hunt for θ13with LENA

subject

description

In a hunt for by far missing neutrino mixing angle ?13 the accelerator experiments have recently indicated non-zero value and the dedicated reactor neutrino experiments are moving towards the data-taking phase to confirm that. The small effect of ?13 to the neutrino oscillation probabilities can be also complementarily probed using artificially made source of mono-chromatic neutrinos with low energies originated from electron capture processes. Due to the small energy of neutrino and tiny interaction cross section, and the expected scale of ?13 support the use of large liquid scintillation detector. In this work, the estimated sensitivities for measurement of mixing angle ?13 is presented in context of proposed LENA detector. Instead of the existing and earlier investigated neutrino source 51Cr, more feasible source candidate 75Se is used. The search for possible sterile neutrino flavors is also discussed.
