Collider Tests of Compact Space Dimensions Using Weak Gauge Bosons

We present collider tests of the recent proposal for weak-scale quantum gravity due to new large compact space dimensions in which only the graviton (G) propagates. We show that the existing high precision LEP-I Z -pole data can impose nontrivial constraints on the scale of the new dimensions, via the decay mode Z{r_arrow}f{ovr f}+G (thinspf=q,thinsp{ell}) . These bounds are comparable to those obtained at high energy colliders and provide the first sensitive probe of the scalar graviton. We also study W(Z)+G production and the anomalous WW(ZZ) signal from virtual G -states at the Fermilab Tevatron and compare them with the LEP-I bound and those from LEP-II and future linear colliders. {copyright} {ital 1999} {ital The American Physical Society}
