The OPERA collaboration has recently announced results which could be interpreted as a measurement of neutrino velocities greater than the speed of light. In this seminar, we will watch a recording of a seminar given at CERN on 23 September by Dario Autiero on behalf of the OPERA collaboration describing the results and the various technical effects which could contribute to the observed anomaly.

Early this year there was great excitement that a new particle may have been discovered by the CDF experiment at Fermilab. This purported particle decayed into two jets, producing a nice mass peak in the Wjj spectrum. Despite an initial CDF claim that the probability of this being an artifact of backgrounds was less than 1 part in 100,000, I will show how we went about demonstrating there is in fact no excess in the CDF Wjj data. Instead, there are some interesting issues with the measurements of single-top-quark production in CDF and D0 data that both explain the Wjj discrepancy, and lead to broader questions about the experimental data sets.
