Measurement of the EMC effect in the deuteron

We determined the structure function ratio R-EMC(d) = 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(EMC)(d)/dx=-0.10 +/- 0.05 in the range of Bjorken x from 0.35 to 0.7, for invariant mass W > 1.4 GeV and Q(2) > 1GeV(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
