Description

We present a study of the dijet invariant mass spectrum in events with at least two jets produced in association with a $W$ boson, using data collected with the D0 detector which correspond to an integrated luminosity of 4.3 fb$^{-1}$. We perform a detailed comparison of the observed distribution with the background prediction, taking into account systematic uncertainties, to check the presence of an excess in the 120-160 GeV region recently claimed by the CDF Collaboration.
