Description
We investigate the reconstruction capabilities of Dark Matter properties from future
ton-scale direct detection experiments using several targets. Adopting realistic
values for the exposure, energy threshold and resolution of Dark Matter experiments
which will come online within 10 years, the degree of complementarity between
different targets is quantified. While a measurement of the Dark Matter mass and
inelastic parameter are promisingly robust, it turns out that scalar, vector and
axial couplings can only be loosely constrained. In our work, the uncertainty in the
astrophysical parameters controlling the local Dark Matter density and velocity
distribution is included self-consistently and translates into a significant
downgrading of accuracy. However, we show that, under certain assumptions, future
direct detection experiments can achieve self-calibration of some astrophysical
parameters, and they will be able to constrain the Dark Matter mass with only very
weak external astrophysical constraints.
