Chaos & Complex Systems Seminar
'Real School' : The tension of standard structures and varied social processes in schools
Time: 12:05 pm
Place: 4274 Chamberlin Hall (Refreshments will be served)
Speaker: Mary Metz, School of Education
Abstract: Over the last century and a half many aspects of schooling, especially secondary schooling, have been standardized and their form, despite some changes, has been remarkably resilient. Patterns of legitimate, “real” school are deeply embedded in social expectations. At the same time, we know that effective teachers create routines and atmospheres that vary widely. Some individual students thrive better with some approaches, others with others. Further, (though less well documented) community context and students’ social class and ethnicity have a big effect on what happens in classrooms. Nonetheless, over the last 35 years, there has been increasing societal pressure to standardize the substance and practice of K-12 education yet further. This presentation explores the reasons for the persistent tension between standardization of routines and the need for wide variation and flexibility in actual instruction inside the classroom.

Theory Seminar (High Energy/Cosmology)
Dark Matter in Dilepton Production
Time: 3:00 pm
Place: 5280 Chamberlin Hall
Speaker: Nirmal Raj, University of Oregon
Abstract: At the LHC a standard search channel for new physics is the production of a pair of leptons. New resonances or contact operators can be gleaned from peaks or broad deviations respectively in the invariant mass distribution (mll) of this channel. I'll demonstrate in this talk how hidden sectors can show up in dileptonic events through radiative corrections to the Standard Model process, giving rise to unique features in mll, as well as in leptonic angular distributions. One compelling possibility that can be probed is that of dark matter with scalar messengers coupling it to the quarks and leptons. I will present constraints from dilepton spectrum measurements at the LHC and dark matter experiments, and make predictions for the bounds from the high luminosity 14 TeV LHC as well as a 100 TeV collider.
