Query: Looking for Lorentz Violation in Short-Range Gravity   General violations of Lorentz symmetry can be described by the Standard-Model
Extension (SME) framework. The SME predicts modifications to existing physics
and can be tested in high-precision experiments. By looking for small
deviations from Newton gravity, short-range gravity experiments are expected to
be sensitive to possible gravitational Lorentz-violation signals. With two
group's short-range gravity data analyzed recently, no nonminimal Lorentz
violation signal is found at the micron distance scale, which gives stringent
constraints on nonminimal Lorentz-violation coefficients in the SME.
