Title: New Results from the NOvA Neutrino Oscillation Experiment
Speaker: Patricia Vahle, Mansfield Professor of Physics at William & Mary
Neutrino oscillations provide the first hints at physics beyond the standard model of particle physics. Current and future neutrino experiments aim to further refine our understanding of neutrino mixing and reveal the remaining unknowns in the process. Precision measurements in long-baseline accelerator experiments could help answer profound questions about the origin and evolution of our universe, including the asymmetry of matter over antimatter.
The NOvA experiment at Fermilab uses a beam of neutrinos and two detectors separated by an 810 km baseline to observe muon neutrino disappearance and electron neutrino appearance. These measurements have the potential to resolve the ordering of the neutrino masses, called the hierarchy, determine whether the mixing angle theta_23 is maximal, and if not, in which octant it lies, as well as hint at the violation of CP in the neutrino sector. Vahle will describe the current status of accelerator oscillation experiments seeking to answer these questions and present new results from the NOvA experiment.
Patricia Vahle got her start in physics at New Mexico State University. She went on to the University of Texas at Austin for her PhD in particle physics. After a postdoc at University College London, she arrived at William and Mary. Patricia is co-spokesperson of the NOvA neutrino experiment
