Abstract

Liquid Argon Time Projection Chambers (LArTPCs) are widely used in particle physics experiments. They use light and charge released in events to reconstruct and analyze them. Light information collected by the Photon Detection System (PDS) is used mainly to determine the initial time stamp, $t_0$, and to support determining the total energy of the event. For these purposes, it is important to simulate and predict the propagation of light inside the detector. There are several approaches to this, and this work discusses some of the options.
