Status and prospects of the NEXT experiment for neutrinoless double beta decay searches
NEXT (Neutrino Experiment with a Xenon TPC) is an experimental program whose
goals are to discover neutrinoless double beta decay using Xe in high
pressure xenon TPCs with electroluminescent readout. In this paper, results
from the NEXT-White detector, which is currently taking data at Laboratorio
Subterr\'aneo de Canfranc (LSC) will be reported. The prospects for the
NEXT-100 apparatus, scheduled to start operations in 2020, as well as the plans
to extend the technology to large and ultra-low background detectors needed to
fully explore the inverse hierarchy of neutrino masses, will also be briefly
discussed.Comment: This article is an expanded version of my contribution to the 2019

Neutrinoless double-beta decay. A brief review
In this brief review we discuss the generation of Majorana neutrino masses
through the see-saw mechanism, the theory of neutrinoless double-beta decay,
the implications of neutrino oscillation data for the effective Majorana mass,
taking into account the recent Daya Bay measurement of theta_13, and the
interpretation of the results of neutrinoless double-beta decay experiments.Comment: 22 page
Summary of Golden Measurements at a -Factory
The precision and discovery potential of a neutrino factory based on muon
storage rings is summarized. For three-family neutrino oscillations, we analyze
how to measure or severely constraint the angle , CP violation,
MSW effects and the sign of the atmospheric mass difference .
The appearance of ``wrong-sign muons'' at three reference baselines is
considered: 732 km, 3500 km and 7332 km. We exploit the dependence of the
signal on the neutrino energy, and include as well realistic background
estimations and detection efficiencies. The optimal baseline turns out to be
(3000 km).Comment: 7 pages, Latex2e, 5 eps figures, use package espfi
