Fitting the annual modulation in DAMA with neutrons from muons and
  neutrinos
  The DAMA/LIBRA experiment searches for evidence of Dark Matter scattering off
nuclei. Data from DAMA show 9.2 sigma evidence for an annual modulation,
consistent with Dark Matter having a cross section around 2x10^(-40) cm^2.
However this is excluded by other Direct Detection experiments. We propose an
alternative source of annual modulation in the form of neutrons, which have
been liberated from material surrounding the detector by a combination of 8B
solar neutrinos and atmospheric muons. The phase of the muon modulation lags 30
days behind the data, however we show that adding the modulated neutrino
component shifts the phase of the combined signal forward. In addition we
estimate that neutrinos and muons need around 1000 m^3 of scattering material
in order to generate enough neutrons to constitute the signal. With current
data our model gives as good a fit as Dark Matter and we discuss prospects for
future experiments to discriminate between the two.
