Abstract
We have placed a torsion balance (containing two Be and two Cu test bodies) on a hillside to search for intermediate-range forces that couple to baryon number. Our results constrain (at 1σ) the strength of such an interaction to be ||α~||<=1×10-4 for ranges 250<=λ<=1400 m and ||α~||<=1×10-3 for ranges 30<λ<250 m.
