Abstract

We have carried out the largest search for stable particles with fractional electric charge, based on an oil drop method that incorporates a horizontal electric field and upward air flow. No evidence for such particles was found, giving a 95% C.L. upper limit of 1.15× 10^-22 particles per nucleon on the abundance of fractional charge particles in silicone oil for 0.18 e ≤ |Q_residual| ≤ 0.82 e.
