NEMO-3 and SuperNEMO double beta decay experiments

Latest results on $\beta\beta 0 \nu$, $\beta\beta 0 \nu\chi^0$ and $\beta\beta 2 \nu$ decays of different isotopes from NEMO-3 double beta decay experiment are presented. In particular, new limits on neurtinoless double beta decay of $^{100}Mo$ and $^{82}Se$ have been obtained, $T_{1/2} > 4.6\times 10^{23}$ y and $T_{1/2} > 1\times 10^{23}$ y, respectively. A possible next step with SuperNEMO detector is discussed.
