Which Way Did It Go? A View From The Top

Recently, the CDF and DZero collaborations completed an intense effort to combine their asymmetry measurements, carefully taking into account the statistical relationships among them. In addition to producing more precise results, they were able to reconcile the differences among the measurements as well as with updated theoretical predictions. The final set of asymmetry results was released and accepted for publication in Physical Review Letters. The summary is shown in the figure. The consistency and precision of the reported measurements represent a true legacy of the Tevatron program.

These scientists are the primary analysts for this result. Top row from CDF collaboration, from left: Ziqing Hong (Northwestern), Dave Toback (Texas A&M) and Jon Wilson (Texas A&M). Bottom row, from DZero collaboration: Andreas Jung (Purdue)
