Search for Large Extra Spatial Dimensions in Dimuon Production with the D0 Detector

Abstract

We present the results of a search for the effects of large extra spatial dimensions in $p\bar{p}$ collisions at $\sqrt{s}=$ 1.96 TeV in events containing a pair of energetic muons. The data correspond to 246 \ipb of integrated luminosity collected by the \D0 experiment at the Fermilab Tevatron Collider. Good agreement with the expected background was found, yielding no evidence for large extra dimensions. We set 95% C.L. lower limits on the fundamental Planck scale between 0.85 TeV and 1.27 TeV within several formalisms. These are the most stringent limits achieved in the dimuon channel to date.
