Title: Measurement of the EMC effect in the deuteron

We have determined the structure function ratio $$R^d_{\rm EMC}=F_2^d/(F_2^n+F_2^p)$$ from recently published $F_2^n/F_2^d$ data taken by the BONuS experiment using CLAS at Jefferson Lab. This ratio deviates from unity, with a slope $$dR_{\rm EMC}^{d}/dx= -0.10\pm 0.05$$ in the range of Bjorken $x$ from 0.35 to 0.7, for invariant mass $W>1.4$ GeV and $Q^2>1$ GeV$^2$. The observed EMC effect for these kinematics is consistent with conventional nuclear physics models that include off-shell corrections, as well as with empirical analyses that find the EMC effect proportional to the probability of short-range nucleon-nucleon correlations.
