Description
The PrimEx experiment at Jefferson Lab aims to extract the η radiative decay width via the Primakoff effect. This process can be seen as the inverse process of the decay of the η-meson into two photons. The experiment collected data on liquid helium target in three different phases, 2019, 2021 and 2022 utilizing the GlueX detector in Hall-D. By extracting a high precision measurement of the radiative decay of this meson, we will be able to obtain information about the ratio of the light quark masses, and the η-η' mixing angle, which will ultimately contribute understand QCD symmetries.
