Kaon condensation in nuclear matter

Using the leading operators in the chiral lagrangian for meson-baryon interactions (at low momentum) and treating the meson fields classically, Kaplan and Nelson have observed, using numerical methods, that a charged kaon condensate forms at several times nuclear density. We derive an analytical exp...

Description
Summary:Using the leading operators in the chiral lagrangian for meson-baryon interactions (at low momentum) and treating the meson fields classically, Kaplan and Nelson have observed, using numerical methods, that a charged kaon condensate forms at several times nuclear density. We derive an analytical expression for the critical density. The effects of virtual mesons and higher dimension operators are discussed. The possibility of a neutral kaon condensate is also considered.
