    "abstract": "The results for meson condensation in the literature vary markedly depending\non whether one uses chiral perturbation theory or the current-algebra-plus-PCAC\napproach. To elucidate the origin of this discrepancy, we re-examine the role\nof the sigma-term in meson condensation. We find that the resolution of the\nexisting discrepancy requires a knowledge of terms in the Lagrangian that are\nhigher order in density than hitherto considered.",
