Search for bb decay with NEMO 3 and SuperNEMO experiments

NEMO 3 is a double beta decay experiment. A part of low background data was analysed, preliminary result on bb2nu decay of 130Te obtained: T_{1/2} = 7.6 +- 1.5(stat) ± 0.8(syst) * 10^{20} y$. No bb0nu signal was observed: T_{1/2}^{0\nu}(100Mo) > 5.8 *10^{23} y and T_{1/2}^{0\nu}(82Se) > 2.1 * 10^{23} y (90% C.L.). SuperNEMO project R&D has started.
