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 4.3fb-1. The observed distribution has an excess in the 120-160GeV/c2 mass range which is not described by current theoretical predictions within the statistical and systematic uncertainties.

Abstract
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 4.3fb-1. The observed distribution has an excess in the 120-160GeV/c2 mass range which is not described by current theoretical predictions within the statistical and systematic uncertainties. In this Letter, we report studies of the properties of this excess. © 2011 American Physical Society.File in questo prodotto:
