Bound on nonlocal scale from LEP

Abstract

Leptons, quarks and gauge bosons are assumed to be described by local field theory. Stringent bounds on nonlocal scale can be derived from the high- presision LEP measurements. We find a bound on nonlocal scale ${\Lambda }_{nl}>1020Gev$, C.L.95\% from LEP data.
