Recent studies on meson condensations (pions and kaons) in high-density hadronic matter are reviewed. After summarizing onset mechanisms of pion and kaon condensations, we discuss implications for neutron star phenomena such as rapid cooling through neutrino emission, static and dynamic properties of neutron stars. Recent studies on coexistence problem of pion and kaon condensations are briefly...
The neutral kaon system can be effectively described by non-unitary, dissipative, completely positive dynamics that extend the usual treatment. In the framework of open quantum systems, we show how the origin of these non-standard time evolutions can be traced to the interaction of the kaon system with a large environment. We find that D-branes, effectively described by a heat-bath of quanta ob...
Recent results obtained by the NA48 Collaboration on rare neutral kaon and hyperon decays are presented. These include measurements performed with the simultaneous KL and KS beams during the " 0 =" programme as well as investigations of rare KS and neutral hyperon decays using high intensity proton beams at the KS target station. Future projects aiming to search for very rare KS decays and to s...
The kaon energy in a nuclear medium and its dependence on kaonnucleon and nucleon-nucleon correlations is discussed. The transition from the Lenz potential at low densities to the Hartree potential at high densities can be calculated analytically by making a Wigner-Seitz cell approximation and employing a square well potential. As the Hartree potential is less attractive than the Lenz one, kaon...
This talk reviews recent progress in formulating the dynamics of Kaon Physics, within the framework of the 1/N c –expansion in QCD.
