摘要：

We perform a global analysis of the lepton-quark neutral current data on the low scale gravity model, which arises from the extra dimensions. The global data include HERA neutral current deep-inelastic scattering, Drell-Yan production at the Tevatron, and fermion pair production at LEPII. The Drell-Yan production, due to the large invariant mass data, provides the strongest constraint. Combining all data, the effective Planck scale must be larger than about 1.12 TeV for n = 3 and 0.94 TeV for n = 4 at 95%CL. (C) 1999 Elsevier Science B.V. All rights reserved.
