At each bunch crossing about 20 soft proton-proton interactions are expected to happen. In order to study new phenomena andimprove our current knowledge of the physics these events must be understood.However, the physics of soft interactions are not completely known at such high en-ergies. Different phenomenological models, trying to explain these interactions, areimplemented in several Monte-Carlo (MC) programs such as PYTHIA, PHOJETand EPOS. Some parameters in such MC can be tuned to improve theagreement with the data.
