Physics Department Colloquium
Precision Muon Physics: Capturing a Moment in a Lifetime
Time: 4:00 pm
Place: 2241 Chamberlin Hall (coffee at 3:30 pm)
Speaker: David Hertzog, University of Illinois at Urbana-Champaign
Abstract: Low-energy, precision measurements are important to establish the parameters of the Standard Model and to test various predictions in the quest for new physics signatures. I will discuss two of our experiments that recently reported first physics results. Both involve the muon lifetime, leading to the Fermi Constant at a new level of precision and the nucleon weak pseudoscalar coupling constant g_P, determined in an unambiguous manner for the first time. Future plans include a Fermilab-based next-generation muon anomalous magnetic moment measurement, which follows on the our effort that has provided one of the strongest hints of physics beyond the Standard Model today.
