    "abstract": "The effective kaon mass in dense baryonic matter is calculated based on PCAC,\ncurrent algebra and the Weinberg smoothness hypothesis. The off-shell behavior\nof the K-N scattering amplitudes is treated consistently with PCAC, and the\neffects of the subthreshold K-N resonances are also included. The effective\nkaon mass is found to depend crucially on the K-N sigma term. Since the current\nestimates of K-N Sigma term are very uncertain, we discuss various scenarios\ntreating K-N Sigma term as an input parameter; for certain values of K-N Sigma\na collective mode of a hyperon-particle-nucleon-hole state appears at high\ndensities, possibly leading to kaon condensation.",
