the Gran Sasso National Laboratory of INFN during four annual cycles (57986 kgday statistics), are analyzed in terms of WIMP annual modulation signature considering a candidate with mixed coupling to ordinary matter.
In this Letter the data, collected by the ≃100 kg NaI(Tl) DAMA set-up deep underground in the Gran Sasso National Laboratory of I.N.F.N. during four annual cycles (57986 kgday statistics), are analyzed in terms of WIMP annual modulation signature considering a candidate with mixed coupling to ordinary matter.
