    "abstract": "The effect of altered hadron masses is studied for its effect with regard to\nfinal-state hadronic observables. It is shown that the final phase space\ndensities of pions and kaons, which can be inferred experimentally, are\nsensitive to in-medium properties of the excited matter at earlier stages of\nthe collision, but that the sensitivity is significantly moderated by\ninteractions that change the effective numbers of pions and kaons during the\nlatter part of the collision.",
