Abstract:
We report on a search for direct Kaluza-Klein graviton
production in a data sample of 84 pb-1 of pp-bar
collisions at sqrt[s]=1.8 TeV, recorded by the Collider
Detector at Fermilab. We investigate the final state of
large missing transverse energy and one or two high
energy jets. We compare the data with the predictions
from a (3+1+n)-dimensional Kaluza-Klein scenario in
which gravity becomes strong at the TeV scale. At 95%
confidence level (C.L.) for n=2, 4, and 6 we exclude an
effective Planck scale below 1.0, 0.77, and 0.71 TeV,
respectively.
