Abstract

Neutrinoless Double Beta Decay is a hypothesised nuclear process in which two neutrons simultaneously decay into protons with no neutrino emission. The prized observation of this decay would point to the existence of a process that violates a fundamental symmetry of the Standard Model of Particle Physics, and would allow to establish the nature of neutrinos. Today, the lower limits on the half-life of this process exceed 10$^{25}$-10$^{26}$ yr. I will review the current status of the searches for Double Beta Decay and the perspectives to enhance the experimental sensitivity in the next years.

answer to question

I thank the Referee for reading carefully my proceeding and improving its quality. I attach my answers to his/her questions:
1) about the schedule of NEXT-100: I wrote "The first mile-stone of the NEXT collaboration should have been the operation of NEXT-100, [..] nevertheless..." and the Referee asked if now NEXT-100 is delayed. I did not mean that NEXT-100 is delayed (even if I have not found recent talks/papers about the status of this project, and the website is not updated, so I can not state that it is on schedule...). I just meant that this step should have been the next step of the collaboration. Nevertheless, they decided to run a medium-scale project before NEXT-100, called NEW (or NEXT-WHITE) and they are now publishing the results obtained with NEW and not with NEXT-100.
2) about AMoRE, the Referee observed (correctly) that they are preparing a 200 kg experiment. I did not mentioned it before because I think it is not going to happen in the immediate future (they are still working on the kg scale), but I understand the point of the Referee, so I added a sentence to clarify that this is not a small R$\&$D, but a part of a long-term plan.
Best regards
Laura
