Description
Investigating the potential feeble interaction between particles in the Standard Model (SM) and the Dark Sector (DS) is a significant frontier in particle physics. One possible manifestation of this feeble interaction is the dark photon, theorized as a vector gauge mediator that interacts very weakly with SM fermions.
The BGOOD photoproduction experiment combines a central electromagnetic calorimeter with a forward spectrometer for charged particle detection. This configuration enables the complete detection of reaction final states such as $\pi^0 p$, $\eta p$, and $2\pi^0 p$. These are well-suited channels for the study of the mass resolution with regard to the dark photon search. The missing mass of the photons from $\eta$ decay were used to determine the mass resolution of the detector. Kinematic fitting techniques are also used to enhance the mass resolution, a critical element for accurate particle identification in high-energy experiments.
