Please let me know if you have comments or suggestions to the preliminary abstract attached at the end of this email. It has to be submitted by this Friday. Thank you, and all the best. Ilya Current Status of the Neutral Pion Polarizability Measurement at Jefferson Lab 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 neutral pion polarizability through 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. -------------- next part -------------- An HTML attachment was scrubbed...
