Scalar dark matter probes the scale of nonlocality

    Scalar dark matter (DM) in a theory introduces hierarchy problems, and suffers from the inability to predict the preferred mass range for the DM. In a WIMP-like minimal scalar DM setup we show that the infinite derivative theory can predict the DM mass and its coupling. The scale of nonlocality (M) in such a theory in its lowermost limit (constrained by LHC) implies a DM mass  TeV and a coupling with the Standard Model (SM) Higgs λHS102. Planned DM direct detection experiments reaching such sensitivity in the DM will effectively translate into lower bounds on the scale at which the nonlocality comes into the play.
