SESZIONE DI TORINO The highly radiopure about 250 kg NaI(Tl) DAMA/LIBRA set-up is
running at the Gran Sasso National Laboratory of the I.N.F.N..
Here first results obtained by this second generation experiment
exploiting the model independent annual modulation signature for
Dark Matter particles in the galactic halo are presented (exposure of
0.53 ton x yr). The DAMA/LIBRA data confirm the evidence for the presence
of Dark Matter particles in the galactic halo as observed by the former
DAMA/NaI
experiment. The combined analysis of the data of the two experiments
(total exposure 0.82 ton x yr) gives a C.L. at 8.2 sigma.
