Upper part: the inelastic cross section extracted from the Glauber analysis (data) in comparison to the inelastic cross section used in the BUU simulation [1, 2]. Lower part: width of the meson in the nuclear medium in the nuclear rest frame as a function of the momentum in a Glauber analysis (squares), from the Giessen BUU model with the inelastic cross section from the upper figure (red dashed line), and after fits to the data of Fig. 2 with the BUU simulation (red solid line) and the Valencia Monte Carlo simulation (blue circle) [3], respectively. Only statistical errors are shown.
