By means of a simple rescaling, modifications of hadron masses and widths are incorporated into the thermal analysis of particle ratios in ultra-relativistic heavy-ion collisions. We find that moderate, up to 20%, changes of hadron masses…

We reply to the Comment by Hatsuda and Lee on our recent paper "Meson Masses in Nuclear Matter" (Phys.Rev.Lett. 78, 1010, (1997)). We argue that, contrary to the claim in the Comment, the short distance operator product expansion is not…
