Current Status of the Neutral Pion Polarizability Measurement at Jefferson Lab

ORAL

Abstract

The electromagnetic polarizability is a key intrinsic property of hadrons, reflecting how their internal structure responds to external fields. Determining the polarizabilities of the lightest hadrons - the pions - offers a stringent test of Quantum Chromodynamics (QCD). The NPP experiment at Jefferson Lab is dedicated to extract the neutral pion polarizability through a high-precision study of Primakoff photoproduction of pion pairs. This talk will present recent advances in the analysis of the experimental data and discuss the ongoing progress toward a determination of the pion polarizability.

*The experiment was supported by Jefferson Science Associates, LLC operated Thomas Jefferson National Accelerator Facility for the United States Department of Energy under U.S. DOE Contract No. DE-AC05-06OR23177
