The noise description in the hadronic calorimeter TileCal represents a very valuable technical job. The second part presents a fruitful physics analysis-- the cross section measurement of the process p + p --> Z0 --> T + T. The Monte Carlo simulations of the TileCal are described in the first part of the thesis, including a detailed treatment of the electronic noise and multiple interactions (so-called pile-up). An accurate description of both is crucial for the reconstruction of e.g. jets or hadronic tau-jets. The second part reports a Standard Model measurement of the Z0 --> T + T process with the emphasis on the final state with an electron and a hadronically decaying tau-lepton. The Z0 --> T+T channel forms the dominant background in the search for Higgs bosons decaying into tau lepton pairs, and thus the good understanding achieved here can facilitate more sensitive Higgs detection.}, url = {http://library.usi.edu/record/695344}, doi = {https://doi.org/10.1007/978-3-319-00810-3}, }
