We report a study of the invariant mass distribution of jet pairs produced in association with a
W boson using data collected with the CDF detector which correspond to an integrated luminosity
of 4.3 fb?1. The observed distribution has an excess in the 120-160 GeV/c2 mass range which is
not described by current theoretical predictions within the statistical and systematic uncertainties.
