Dark matter electromagnetic dipoles: the WIMP expectation

  title={Dark matter electromagnetic dipoles: the WIMP expectation},

Abstract 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 four-fermion interactions with Standard Model (SM) charged fermions. Related to their loop nature these moments can largely depend on the UV completion at the origin of the four-fermion operators. We illustrate this property by considering explicitly two simple ways to generate these operators, from t- or s-channel tree-level exchange… Expand

Dark matter produced from neutrinos
In the presence of interactions between neutrinos and dark matter (DM), DM can potentially be produced via freeze-in from the neutrino sector. We investigate the implications of such a scenario forExpand

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
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
Dipolar dark matter
If dark matter (DM) has nonzero direct or transition, electric or magnetic dipole moment then it can scatter nucleons electromagnetically in direct detection experiments. Using the results fromExpand
Electromagnetic properties of dark matter: Dipole moments and charge form factor
Abstract A neutral dark matter particle may possess an electric dipole moment (EDM) or a magnetic dipole moment (MDM), so that its scattering with nuclei is governed by electromagnetic interactions.Expand

Constraints on dark matter from colliders
We show that colliders can impose strong constraints on models of dark matter, in particular, when the dark matter is light. We analyze models where the dark matter is a fermion or scalar interactingExpand
Direct and indirect limits on the electro-magnetic form factors of WIMPs
Abstract We use the results of direct and indirect searches for weakly interacting massive particles (WIMPs) to obtain bounds on various electro-magnetic form factors of WIMPs. The limits on theExpand
