Hadronic Interaction Vertices Analysis with the ATLAS Detector

The ATLAS detector is able to reconstruct hadronic interaction vertices inside the pixel detector, and with the use of information about the energy deposit of secondary hadrons in subsequent layers of pixel detector (dE/dX), the secondary particle species can be identified (pions can be separated from protons and kaons). The goal of this project is to study the properties of secondary hadrons from interactions of primary particles in specific layers of the pixel detector. In particular, to provide information about the species of the secondary particles that may assist in the tuning of the numerical models used to simulate these interactions.
