Abstract:  We present 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 corresponds to an integrated luminosity of
4.3 fb^{-1}. The observed distribution has an excess in the 120-160
GeV/c^{2} mass range which is not described by current theoretical
predictions within the statistical and systematic uncertainties. In
particular we will discuss the properties of this excess.
