We consider the production of high invariant mass jet pairs at hadron colli
ders as a test for TeV scale gravitational effects. We find that this signa
l can probe effective Planck masses of about 10 TeV at the CERN LHC with a
center of mass energy of 14 TeV and 1.5 TeV at the Fermilab Tevatron with a
center of mass energy of 2 TeV. These results are compared to analogous sc
attering processes at leptonic colliders.
