| الوصف: | International audience; We study a Dirac Dark Matter (DM) particle interacting with ordinary matter via a pseudo-scalar portal, and analyze its impact on direct detection experiments. This candidate can accommodate the long-standing DAMA modulated signal and yet be compatible with all exclusion limits at 99S% CL. This result holds for natural choices of the pseudo-scalar-quark couplings, and give rise to a significant enhancement of the DMproton coupling with respect to the coupling to neutrons. The model could be tested with measurements of rare meson decays, flavor changing processes, and searches for axion-like particles with mass in the MeV range. |
