The Physics & Astronomy Colloquium Series presents Leah Broussard of Oak Ridge National Lab, discussing "A Broader View of Neutron Beta Decay from the Nab Experiment at ORNL(Oak Ridge National Laboratory)" on November 21.

Abstract: The weak force of nature uniquely allows quarks to change flavor, resulting in the transformation of nuclei known as nuclear beta decay. Currently, measurements of the weak mixing of quarks are in tension with the Standard Model's description, a discrepancy referred to as the "Cabibbo Angle Anomaly." As the simplest nucleus to undergo beta decay, the neutron has emerged as a system which can provide a competitive measurement and shine light on this anomaly if experimental uncertainties in the neutron dataset can be improved.
