"Exploring Majorana Landscape: the NEXT Generation"
Neutrinos may be Majorana particles. If so, neutrino less double beta decay processes could be observed by the next generation of bb0nu experiments. I will briefly review the state of the art, then discuss one of the most promising ideas in the field, the use of Hight Pressure Gas Xenon TPC (HPGXe) with electroluminescence gain and optical readout. A 100 kg incarnation of such a device will start operations at the Canfranc Underground Lab in Spain in late 2013 or early 2014. The technology can be extrapolated to 1 ton, and thus lead the exploration of the inverse hierarchy in Majorana landscape.
