  Deviations from Newton's Inverse-Squared Law at the micron length scale are
smoking-gun signals for models containing Supersymmetric Large Extra Dimensions
(SLEDs), which have been proposed as approaches for resolving the Cosmological
Constant Problem. Just like their non-supersymmetric counterparts, SLED models
predict gravity to deviate from the inverse-square law because of the advent of
new dimensions at sub-millimeter scales. However SLED models differ from their
non-supersymmetric counterparts in three important ways: (i) the size of the
extra dimensions is fixed by the observed value of the Dark Energy density,
making it impossible to shorten the range over which new deviations from
Newton's law must be seen; (ii) supersymmetry predicts there to be more fields
in the extra dimensions than just gravity, implying different types of
couplings to matter and the possibility of repulsive as well as attractive
interactions; and (iii) the same mechanism which is purported to keep the
cosmological constant naturally small also keeps the extra-dimensional moduli
effectively massless, leading to deviations from General Relativity in the far
infrared of the scalar-tensor form. We here explore the deviations from
Newton's Law which are predicted over micron distances, and show the ways in
which they differ and resemble those in the non-supersymmetric case.
