The effect of hydrodynamical simulation inspired dark matter velocity
  profile on directional detection of dark matter
  Directional detection is an important way to detect dark matter. An input to
these experiments is the dark matter velocity distribution. Recent
hydrodynamical simulations have shown that the dark matter velocity
distribution differs substantially from the Standard Halo Model. We study the
impact of some of these updated velocity distribution in dark matter
directional detection experiments. We calculate the ratio of events required to
confirm the forward-backward asymmetry and the existence of the ring of maximum
recoil rate using different dark matter velocity distributions for $^{19}$F and
Xe targets. We show that with the use of updated dark matter velocity profiles,
the forward-backward asymmetry and the ring of maximum recoil rate can be
confirmed using a factor of $\sim$2 - 3 less events when compared to that using
the Standard Halo Model.
