Description
The preferred solution of the atmospheric and solar neutrino problems via
neutrino flavour oscillations requires the extension of the Standard Model
(SM) with neutrino masses. Being gauge singlets, the appealing possibility of
Majorana masses is only open to neutrinos amongst all the SM particles.
Neutrinoless double beta decay is regarded as the best experimental probe of
the Majorana character of neutrino masses. In the first part of the session
we will review the possible extensions of the SM that can lead to Majorana
masses for neutrinos and discuss their contributions to neutrinoless double
beta decay (Enrique). The second part of the session will summarize the
results from arXiv:0907.3143, where the smallness of neutrino masses is
explained through high dimension operators with TeV scale mediators (Florian).
