"Simulation of the full noise pattern in Tile Calorimeter Front End electronics: a phenomenological approach to coherent effects"

The noise pattern in the high gain read-out of the TileCal front-end electronics is simulated including correlations. A basic comparison with test beam data is carried out. The limits and potentialities of the current approach are discussed. A preliminary extrapolation to simulated QCD di-jet events implies that, on average, the correlated noise component can increase TileCal noise contribution to the jet energy by about 87\% on average, while the total calorimeters noise is expected to remain between 2\% to 4\% of the total jet energy. An initial strategy for analysing and incorporating these effects during LHC data-taking, particularly in the early phase, is also outlined.
