Some Thoughts on (the Incompleteness of) the (Double) Differential Event Rates for Elastic WIMP-Nucleus Scattering in (Directional) Direct Dark Matter Detection Physics

Abstract

In this paper, we revisit the expressions for the (double) differential event rates for elastic WIMP-nucleus scattering and discuss some unusual thoughts on (the incompleteness of) the uses of these expressions in (directional) direct Dark Matter detection physics. Several not-frequently mentioned (but important) issues will be argued and demonstrated in detail.
