We report new constraints on extra-dimensional models and other physicsbeyond the Standard Model based on measurements of the Casimir force betweentwo dissimilar metals for separations in the range 0.2--1.2 $\mu$m. The Casimirforce between an Au-coated sphere and a Cu-coated plate of amicroelectromechanical torsional oscillator was measured statically with anabsolute error of 0.3 pN. In addition, the Casimir pressure between twoparallel plates was determined dynamically with an absolute error of $\approx0.6$ mPa. Within the limits of experimental and theoretical errors, the resultsare in agreement with a theory that takes into account the finite conductivityand roughness of the two metals. The level of agreement between experiment andtheory was then used to set limits on the predictions of extra-dimensionalphysics and thermal quantum field theory. It is shown that two theoreticalapproaches to the thermal Casimir force which predict effects linear intemperture are ruled out by these experiments. Finally, constraints on Yukawacorrections to Newton's law of gravity are strengthened by more than an orderof magnitude in the range 56 nm to 330 nm.Comment: Revtex 4, 35 pages, 14 figures in .gif format, accepted for  publication in Phys.
