Last Friday I was in Pisa, at the Scuola Normale Superiore (see picture), where italian members of the CMS Collaboration gathered for two days to discuss the status of their studies, exchange ideas, and try to coalesce common analysis efforts.

W bosons are amazingly interesting objects. Almost thirty years after their discovery -by Carlo Rubbia and his collaborators of the UA1 experiment at CERN- they continue to provide critical information on the theory of electroweak interactions. The front of particle physics has moved quite a bit further from 1983, and yet the weapons we use todat to try and conquer unexplored land have not changed much. Today I wish to summarize one particular search that has been done by the CDF experiment at the Tevatron proton-antiproton collider, one which tries to catch W bosons as they decay in a very uncommon way.
