  2. First:Update on half-life of 2nbb The result I presented in Manchester meeting was before shifting the foil (although I mistakenly thought it was after shifting the foil!) So now my half-life is 9.36 x 1018 (compare to 9.61 x1018) before shift. Fortounatly still phase I and phase II still have a good agreement (9.42 and 9.34) But I am a bit worry about tof cut because it gives slightly different value of half-life each time I run the code… so this 9.36 can change up to 9.39. Is that anyway to avoid this?

  3. Limit on 0nbb and 0nbbrc • To set limit on those two I re-measured half-life (normalization factor) for Esum<2.5 and then set limit on 0nbb and 0nbbrc for Esum>2.5 at 90% CL 0nbb Eff=19% N<3.33 T1/2=1.45 x 1022 0nbrc Eff=11% N<3.29 T1/2= 1.27 x1022

  4. For different majoron modes half-life majaron modes Esum<2.0 MeV 9.37+0.27 - 0.25 X1018 1 Esum<1.5 9.31 +0.37 - 0.32 X1018 2,3 Esum>2.1 MeV 8.84 +0.79 - 0.67 X1018 7

  5. Results Eff N Half-life M1 14% <13.99 > 2.64 x 1021 M2 12% <36.19 > 8.75 x 1020 M3 10% <57.54 > 4.59 x1020 M7 4.9% <266.72 > 4.85 X1019
