Abstract:

The search for large extra spatial dimensions at hadron colliders was performed by looking for effects of virtual Kaluza-Klein gravitons in the production of dielectrons and diphotons at high energies. No evidence was found for large extra dimension (ED). A model-independent 95% C.L. upper limit of 0.46 TeV-4 was set on the parameter nG.
