Phys. Rev. Lett. 102, 171101 (2009) [4 pages]Limits on Nonstandard Forces in the Submicrometer RangeReceived 8 August 2008; published 30 April 2009 We report the search for a nonstandard force by measuring the Casimir forces in the 0.48–6.5 μm range. By comparing the data and the theory of the Casimir force, we have obtained constraints for the parameter α of the Yukawa-type deviations from Newtonian gravity. The obtained limits are more stringent than previous limits in the 1.0–2.9 μm range. Furthermore, we have obtained lower limits for the fundamental scale M* for gauged baryon number in the bulk. In particular, for six extra dimensions, the limits on M* are stringent in the range 6.5×10-6<ρ<2.5×10-4. © 2009 The American Physical Society URL:
