Dark antiatoms can explain DAMA
We show that the existence of a sub-dominant form of dark matter, made of dark “antiatoms” of massm ∼ 1 TeV and size ȧ0 ∼ 30 fm, can explain the results of direct detection experiments, with a positive signal in DAMA/NaI and DAMA/LIBRA and no signal in other experiments. The signal comes from the binding of the dark antiatoms to thallium, a dopant in DAMA, and is not present for the constituent...
متن کاملCan quantum theory explain dark matter?
Certain solutions to a gravitational form of Schrodinger’s equation can yield stable, macroscopic eigenstate solutions having no classical analogue, with properties resembling those of dark matter. Some more tractable solutions show: (1) radiative lifetimes far exceeding the universe’s age, implying negligible emission and inherent stability w.r.t. gravitational collapse, (2) negligible interac...
متن کاملDAMA and WIMP dark matter
We study whether spin-independent scattering of weakly-interacting massive particles (WIMPs) with nuclei can account for the annual modulation signal reported by DAMA. We consider both elastic and inelastic scattering processes. We find that there is a region of WIMP parameter space which can simultaneously accommodate DAMA and the null results of CDMS, CRESST, and XENON. This region correspond...

متن کاملDecaying Dark Matter can explain the e± excesses
PAMELA and ATIC recently reported excesses in e± cosmic rays. Since the interpretation in terms of DM annihilations was found to be not easily compatible with constraints from photon observations, we consider the DM decay hypothesis and find that it can explain the e± excesses compatibly with all constraints, and can be tested by dedicated HESS observations of the Galactic Ridge. ATIC data indi...
