“…DM is electrically neutral, but coupling to the photon through higher multipole interactions is possible [11,[27][28][29][30][31][32][33][34][35][36][37]. Many couplings have been studied, such as anapole moment [37][38][39][40][41], magnetic [30,37,[42][43][44] and electric [30,44] dipole moments, and with a millicharge [45][46][47][48][49][50]. These photon-mediated interactions could be relevant for low WIMP masses, O(1-10)-GeV/c 2 [51].…”

Many compelling models predict dark matter coupling to the electromagnetic current through higher multipole interactions, while remaining electrically neutral. Different multipole couplings have been studied, among them anapole moment, electric and magnetic dipole moments, and millicharge. This study sets limits on the couplings for these photon-mediated interactions using nonrelativistic contact operators in an effective field theory framework. Using data from the PICO-60 bubble chamber leading limits for dark matter masses between 2.7 GeV/c 2 and 24 GeV/c 2 are reported for the coupling of these photon-mediated dark matter-nucleus interactions. The detector was filled with 52 kg of C3F8 operating at thermodynamic thresholds of 2.45 keV and 3.29 keV, reaching exposures of 1404 kg-day and 1167 kg-day, respectively.

The dynamics of an anapole seen as dark matter at low energies is studied by solving the Schrödinger-Pauli equation in a potential involving Dirac-delta and its derivatives in threedimensions. This is an interesting mathematical problem that, as far as we know, has not been previously discussed. We show how bound states emerge in this approach and the scattering problem is formulated (and solved) directly. The total cross section is in full agreement with independent calculations in the standard model.
