Impact of Electronic Detector Noise on Particle Reconstruction in ePIC

The Electron Ion Collider (EIC) is being built at Brookhaven National Laboratory. The Electron-Proton/Ion Collider (ePIC) experiment is being developed in parallel, to collect data from the collisions of electrons with protons and ions. ePIC will use Monolithic Silicon Pixel detectors to track particle trajectories in a solenoidal magnetic field. We have been developing the reconstruction algorithm for charged particles traversing the silicon detector layers, and testing its performance. The tests involve simulations of deep inelastic scattering of electrons from proton beams, and studies of the reconstruction efficiency and purity as a function of the particles’ transverse momentum and pseudorapidity. I will show how the presence of electronic noise in the silicon pixels affects the reconstruction, comparing the efficiency and purity of the reconstruction performance with and without noise implementation.
