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 4.3 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 this letter we report studies of the properties of this excess.

    • The New York Times has thankfully started to link to sources and papers and actually does so in this article. Here is the paper: http://arxiv.org/abs/1104.0699 Links in the text are always a bit cryptic, it would help if they were to put an info box at the end of articles with…
