Mr Nicki Bornhauser (University of Bonn)
We examined an until now unexplained CDF measurement of multi-muon events (arXiv:0810.5357v2). We investigate whether similar events could (and should) have been seen in already completed experiments. The bulk of the CDF data can be reproduced by a simple model; a correct description of events with more than two muons requires a more complicated model. We conclude that the CDF measurement is (at least partly) wrong.
