Cuoricino results for 2 decay to the first excited state 0 + Sergio Di Domizio for the Cuoricino Collaboration Università and INFN Genova Athens, June
Cuoricino Cuoricino collected data at the Laboratori Nazionali del Gran Sasso between 2003 and 2008 It is an array of 5x5x5 cm 3 TeO 2 cryogenic bolometers devoted to the search of 0 decay in 130 Te Cuoricino has a mass of 42 kg (11.8 kg in 130 Te) The accumulated statistics is 19.8 kgy in 130 Te The average energy resolution is 7 keV FWHM at 2.6 MeV
130 Te 2 decay to the excited state 0 + T 1/2 > 1.4 x y (90% C.L.) 2 de-excitation s emitted Coincidence based analysis: strong background reduction CUORICINO RESULT: More details in the poster
