Exploring the Mirror Matter Interpretation of the Dama Experiment: Has the Dark Matter Problem Been Solved?
نویسنده
چکیده
The self consistency between the impressive DAMA annual modulation signal and the measured recoil energy spectrum is identified as an important test for dark matter candidates. Mirror matter-type dark matter passes this test while other dark matter candidates, including standard WIMPs and mini-electric charged particle dark matter , fail. We argue that the unique properties of mirror matter-type dark matter seem to be just those required to fully explain the data, suggesting that the dark matter problem has finally been solved.

Mirror dark matter interpretation of the DAMA/Libra annual modulation signal
The DAMA/Libra experiment has recently confirmed the annual modulation signal obtained in the earlier DAMA/NaI experiment, providing strong evidence that they have actually detected dark matter. We examine the implications of this experiment for the mirror dark matter candidate. We show that mirror dark matter successfully explains the latest DAMA/Libra data, whilst also being consistent with t...
متن کاملMirror dark matter and the new DAMA / LIBRA results : A simple explanation for a beautiful experiment
Recently, the DAMA/LIBRA experiment has convincingly confirmed the DAMA/NaI annual modulation signal, experimentally demonstrating the existence of non-baryonic dark matter in the halo of our galaxy. Meanwhile, in another part of town, other experiments such as CDMS and XENON10 have not detected any evidence for dark matter. One promising dark matter candidate which can reconcile the positive D...
متن کاملReconciling the positive DAMA annual modulation signal with the negative results of the CDMS II experiment
We examine the recent CDMS II results in the context of the mirror matter interpretation of the DAMA/NaI experiment. We find that the favoured mirror matter interpretation of the DAMA/NaI experiment – a He ′ /H ′ dominated halo with a small O ′ component is fully consistent with the null results reported by CDMS II. While the CDMS II experiment is quite sensitive to a heavy F e ′ component, and...
متن کاملImplications of the DAMA and CRESST experiments for mirror matter-type dark matter
Mirror atoms are expected to be a significant component of the galactic dark matter halo if mirror matter is identified with the non-baryonic dark matter in the Universe. Mirror matter can interact with ordinary matter via gravity and via the photon-mirror photon kinetic mixing interaction – causing mirror charged particles to couple to ordinary photons with effective electric charge ǫe. This m...
متن کاملImplications of the DAMA / NaI and CDMS experiments for mirror matter - type dark matter
We re-analyse the implications of the DAMA/NaI experiment for mirror matter-type dark matter, taking into account information from the energy dependence of the DAMA annual modulation signal. This is combined with the null results from the CDMS experiment, leading to fairly well defined allowed regions of parameter space. The allowed regions of parameter space will be probed in the near future b...
