Abstract
We present the results of searches for large extra dimensions in samples of events with large missing transverse energy E(T) and either a photon or a jet produced in pp collisions at s=1.96 TeV collected with the Collider Detector at Fermilab II. For gamma+E(T) and jet+E(T) candidate samples corresponding to 2.0 and 1.1 fb(-1) of integrated luminosity, respectively, we observe good agreement with standard model expectations and obtain a combined lower limit on the fundamental parameter of the large extra dimensions model M(D) as a function of the number of extra dimensions in the model.
