Investigating the DAMA annual modulation data in a mixed coupling framework

In this Letter the data, collected by the similar or equal to 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 kg day statistics), are analyzed in terms of WIMP annual modulation signature considering a candidate with mixed coupling to ordinary matter.
