"Neutron Electromagnetic Form Factor Ratio Measurement using Recoil Polarimetry"Bhasitha Thuthimal Dharmasena Purijjala Lindagawa Gedara , University of Virginia [Host: Chris Neu & Nilanga Liyanage]
ABSTRACT:
The Super BigBite Spectrometer (SBS) program at Jefferson Lab aims to measure nucleon electromagnetic form factors (EMFFs) at high momentum transfers. The GEn-RP experiment, the third in the SBS experiment series, concluded data taking in May 2024. This experiment is focused on measuring the neutron EMFF ratio GnE/GnM through recoil polarimetry at a Q2 = 4.5 (GeV/c)². Two polarimetry techniques have been used in this experiment: charge-exchange np→pn with a passive Fe analyzer, and conventional np→np scattering with an active CH analyzer. The results of this experiment will serve to optimize future even higher Q2 experiments aimed at measuring GnE/GnM. An overview of the experiment and post- experiment data analysis efforts will be presented. |
