Description
From an assumed signal in a Dark Matter (DM) direct detection experi-
ment a lower bound on the product of the DM–nucleon scattering cross section and the
local DM density is derived, which is independent of the local DM velocity distribu-
tion. This can be combined with astrophysical determinations of the local DM density.
Within a given particle physics model the bound also allows a robust comparison of a
direct detection signal with limits from the LHC. Furthermore, the bound can be used
to formulate a condition which has to be fulfilled if the particle responsible for the
direct detection signal is a thermal relic, regardless of whether it constitutes all DM or
only part of it. We illustrate the arguments by adopting a simplified DM model with
a Z mediator and assuming a signal in a future xenon direct detection experiment.
