We study a fermionic Dark Matter particle carrying magnetic dipole moment and analyze its impact on direct detection experiments. In particular we show that it can accommodate the DAMA, CoGeNT and CRESST experimental results. Assuming conservative bounds, this candidate is shown not to be ruled out by the CDMS, XENON and PICASSO experiments. We offer an analytic understanding of how the long-range interaction modifies the experimental allowed regions, in the cross section versus Dark Matter… Expand

New Directions in Direct Dark Matter Searches
I present the status of direct dark matter detection with specific attention to the experimental results and their phenomenological interpretation in terms of dark matter interactions. In particularExpand
Anapole dark matter
Abstract We consider dark matter (DM) that interacts with ordinary matter exclusively through an electromagnetic anapole, which is the only allowed electromagnetic form factor for Majorana fermions.Expand
Dark matter electromagnetic dipoles: the WIMP expectation
We perform a systematic study of the electric and magnetic dipole moments of dark matter (DM) that are induced at the one-loop level when DM experiences fourfermion interactions with Standard ModelExpand
Constraint on Light Dipole Dark Matter from Helioseismology
We investigate the effects of a magnetic dipole moment of asymmetric dark matter (DM) in the evolution of the Sun. The dipole interaction can lead to a sizable DM scattering cross section even forExpand
Direct detection signals of dark matter with magnetic dipole moment
A neutral dark matter (DM) particle with a magnetic dipole moment has a very different direct detection phenomenology with respect to standard candidates. This is due to the peculiar functional formExpand
Loopy constraints on leptophilic dark matter and internal bremsstrahlung
A sharp and spatially extended peak in an astrophysical gamma ray spectrum would provide very strong evidence for the existence of dark matter (DM), given that there are no known astrophysicalExpand
Faint light from dark matter: classifying and constraining dark matter-photon effective operators
A bstractEven if Dark Matter (DM) is neutral under electromagnetism, it can still interact with the Standard Model (SM) via photon exchange from higher-dimensional operators. Here we classify theExpand
Direct detection and solar capture of spin-dependent dark matter

In an extended effective operator framework, we investigate in detail the effects of light mediators on the event spectra of dark matter (DM)-nucleus scatterings. The presence of light mediatorsExpand

Direct detection of dark matter in models with a light Z′
We discuss the direct detection signatures of dark matter interacting with nuclei via a new neutral gauge boson Z′, focussing on the case where both the dark matter and the Z′ have mass of a few GeV.Expand
Collider Constraints on Dipole-Interacting Dark Matter
Dark matter which interacts through a magnetic or electric dipole moment is an interesting possibility which may help resolve the discrepancy between the DAMA annual modulation signal and the nullExpand
Shedding Light on Dark Matter: A Faraday Rotation Experiment to Limit a Dark Magnetic Moment
A Faraday rotation experiment can set limits on the magnetic moment of a electrically-neutral, dark-matter particle, and the limits increase in stringency as the candidate-particle mass decreases.Expand
Dark atoms: asymmetry and direct detection
We present a simple UV completion of Atomic Dark Matter (aDM) in which heavy right-handed neutrinos decay to induce both dark and lepton number densities. This model addresses several outstandingExpand
Direct Detection of Dark Matter Electromagnetic Dipole Moments
Dark matter candidates with electromagnetic dipole moments can arise as dark baryons in gauge-mediated or technicolor models. These dark matter candidates interact with nuclei in direct detectionExpand

Light dark matter versus astrophysical constraints
Abstract Hints of direct dark matter detection coming from the DAMA, CoGeNT experiments point toward light dark matter with isospin-violating and possibly inelastic couplings. However an array ofExpand
Experimental constraints on a dark matter origin for the DAMA annual modulation effect.
A new type of germanium detector is employed to conclusively rule out a standard isothermal galactic halo of weakly interacting massive particles as the explanation for the annual modulation effect leading to the claim of dark matter interactions in the DAMA experiment. Expand
