The Standard Model (SM) of particle physics consists in a description of all the known elementary
particles and their interactions. As far as it is known, the SM has passed all experimental tests, but
presents some imperfections having no explanation for such as the presence of neutrino masses and
the hierarchy problem. This encourages to probe theories beyond the Standard Model (BSM) that
could bring solutions to these problems. An interesting proposal is to search for neutral long lived
particles (LLPs). These type of particles have long decay lengths, can be generated by a variety of
BSM models and could be detected in collider experiments by searching for displaced signals. The
detection of the decay products of LLPs decays will contribute to the discovery of new physics.
The objective of this work is to upgrade and optimize the PUCP Toy Detector presented in [1],
adapting the simulation to the ATLAS detector and adding new features as a Geant4 simulation
of the calorimeter for calculating the energy deposits. And validating it by reproducing the result
of the searches presented in [2]. We conclude that the PUCP Toy Detector is valid, well implemented,
and will be a competitive tool for searching new models containing LLPs decaying inside
the calorimeters in the future.
