Anapole Dark Matter after DAMA/LIBRA-phase2
  We re-examine the case of anapole dark matter as an explanation for the DAMA
annual modulation in light of the DAMA/LIBRA-phase2 results and improved upper
limits from other DM searches. If the WIMP velocity distribution is assumed to
be a Maxwellian, anapole dark matter is unable to provide an explanation of the
DAMA modulation compatible with the other searches. Nevertheless, anapole dark
matter provides a better fit to the DAMA-phase2 modulation data than an
isoscalar spin-independent interaction, due to its magnetic coupling with
sodium targets. A halo-independent analysis shows that explaining the DAMA
modulation above 2 keVee in terms of anapole dark matter is basically
impossible in face of the other null results, while the DAMA/LIBRA-phase2
modulation measurements below 2 keVee are marginally allowed. We conclude that
in light of current measurements, anapole dark matter does not seem to be a
viable explanation for the totality of the DAMA modulation.
