Abstract
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 → ff¯ + G(f = q, l). 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.
