Abstract
In a recent paper, Eletsky and Ioffe estimated the energy shift of -meson with high momentum (q) in nuclei using the Glauber approximation. They also made remarks on the low q vector mesons in medium. In this Comment, we will discuss the second point and show that (i) mean-field physics for the mass shift of low-q mesons is overlooked in the paper, and (ii) the short distant operator product expansion is relevant to analyze the low-q mesons in QCD sum rules contrary to the claim in the paper.
