Measuring Leptonic CP Violation in Neutrinoless Double Beta Decay

We investigate under which circumstances one can show the existence of leptonic CP violation with the help of a positive or negative signal in neutrinoless double beta decay. The possibilities of cancellations are investigated for all mass hierarchies. The non-maximality of the angle connected with the solar neutrino problem in case of the LMA solution allows to make several useful statements. The four different CP conserving possibilities are analyzed. It is implemented how precisely the oscillation parameters will be known after current and future experiments have taken data. The area in parameter space, in which CP violation has to take place, is larger for the inverse mass scheme. We comment on the possibility to probe the Majorana phases in other processes and on their connection to leptogenesis."
