Since the proposal of the Borexino project in the early nineties, the idea to perform a neutrinoless double beta decay experiment with 136Xe dissolved in the scintillator was considered. The beautiful results obtained by the Borexino experiment, which achieved a purity far exceeding design goals, and a new concept for dissolving large quantities of xenon in the scintillator by increasing its pressure make this possibility even more interesting for a new-generation experiment in the next decade. We present the ongoing R&D studies to look for neutrinoless double beta decay using liquid scintillators, discussing the optical properties of the Borexino scintillator when xenon is dissolved in large quantity and with high pressure.

Abstract
Since the proposal of the Borexino project in the early nineties, the idea to perform a neutrinoless double beta decay experiment with 136Xe dissolved in the scintillator was considered. The beautiful results obtained by the Borexino experiment, which achieved a purity far exceeding design goals, and a new concept for dissolving large quantities of xenon in the scintillator by increasing its pressure make this possibility even more interesting for a new-generation experiment in the next decade. We present the ongoing R&D studies to look for neutrinoless double beta decay using liquid scintillators, discussing the optical properties of the Borexino scintillator when xenon is dissolved in large quantity and with high pressure.
