High Energy Seminar
Model Independent Searches in Leptonic Final States at D0
Time: 4:00 pm
Place: 5310 Chamberlin
Speaker: Joel Piper, Michigan State University
Abstract: This presentation reports on model independent searches at the D0 experiment using a subset
of data from Run IIa of the Tevatron containing high-pT objects. The data is divided into non-overlapping
final states and carefully compared to the Standard Model prediction. This approach complements modeldependent searches by scanning systematically across many final states some which would otherwise be
considered only within the context of very specific models or not considered at all. Once all effects due
to SM implementation, detector modeling and statistical fluctuations are taken into account, we look for
deviations which could indicate the presence of physics beyond the Standard Model.

Chaos & Complex Systems Seminar
The cosmic history of supermassive black holes
Time: 12:05 pm
Place: 5310 Chamberlin (Refreshments will be served)
Speaker: Amy Barger, UW Department of Astonomy
Abstract: The early universe was dominated by a small number of giant galaxies containing colossal black
holes and prodigious bursts of star formation. More recently, the creation of stars and the accretion of
material into black holes has been taking place in a large number of medium-size and small galaxies. I
will present observations made at many different wavelengths that show this vast downsizing of cosmic
activity.
