Chiral perturbation in dense matter and meson condensation controversy
arXiv:nucl-th/9407034
Abstract
An outstanding problem in the study of possible kaon condensation is the striking discrepancy between the results of chiral perturbation theory and those of the PCAC-plus-current-algebra approach. I discuss here what causes this discrepancy and what needs to be done to solve the problem. In addition, I point out the importance of examining the validity of the non-relativistic approximation universally employed in the existing treatments of kaon condensation.
