Simulation of a radial TPC for the detection of neutrinoless double beta decay
Original language description
To search for beta beta 0 nu decay with unprecedented sensitivity, the R2D2 collaboration is developing a radial time projection chamber with a fiducial mass of half a tonne of Xe-136 at high pressure. The various approaches implemented to eliminate the radioactive background are presented in terms of detector design, topological recognition of interactions, and event energy reconstruction. The developed tools enable the disentangling of the sought-after signal from the background. The projected sensitivity after ten years of data taking yields a half-life limit exceeding 1027 years, along with a constraint on the effective neutrino mass m(beta beta) that could cover a large fraction of the inverted mass hierarchy region, depending on the final experimental background.
