Title: From Asymmetries to Antimatter
Abstract
ISU's intermediate energy nuclear physics group is presently involved in several fundamental physics measurements. This talk will describe two ongoing measurements involving the first excited state of the proton, the Delta resonance. The Delta resonance is a fertile testing ground to probe the response of a nucleon to electro-magnetic probes. It has been common to describe the excitation of the nucleon in terms of a spin flip induced by an electromagnetic probe. Recently however, there has been increasing interest in a second means by which has resulted in interesting questions on how the quarks within a nucleon contribute to the physical properties of a nucleon such as its spin.
