Abstract
The authors have used a rotating torsion balance to search for feeble forces arising from exchange of ultralow-mass bosons. Their limits on the differential horizontal acceleration of Be/Al or Be/Cu test-body pairs in the field of the Earth, ∆a⊥ = (1.5±2.3)×10-11 cm s-2 and ∆a⊥ = (0.9±1.7)×10-11 cm s-2, respectively, set improved bounds on interactions mediated by bosons with masses ranging between 10-17 and 10-6eV.
