Detecting Dipolar Dark Matter in Beam Dump Experiments

We study interaction of low mass dark matter within beam dump experiments. In particular we study the dipolar dark matter model which assumes that the dark matter couples to Standard Model particles via its electric or magnetic dipole moment. We analyse the constraints on this model in the context of a particular beam dump experiment E613 conducted in the Fermilab. We find that dark matter mass in the range of $1-10$ GeV with a magnetic dipole moment between $(0.33-1.5)\times 10^{-7}μ_B$ and a electric dipole moment between $(0.5-3)\times 10^{-17}$ e-cm. We compare the bounds from other experimental data, such as helioseismological data and direct detection experiments.
