the elementary reaction of kaon exclusive electroproduction on protons has been studied ina broad kinematical range. data for the calculation of the form factor of the kaon have been taken atdifferent values of the invariant center of mass energy w in the range w=1.8, 1.85, 1.98, 2.08 (gev), forone value of the transferred 4-momentum q2=2.35 (gev/c)2. in this analysis, we calculated σl and σt b...

Possibility of kaon-condensed phase in hyperon-mixed matter is considered on the basis chiral symmetry for kaon-baryon and kaon-kaon interactions, being combined with relativistic mean-field theory two-body baryon interaction. In addition, universal three-baryon repulsive force string-junction model phenomenological three-nucleon attractive are introduced. It shown that softening equation state...

We considered the kaon absorption from atomic states into nucleus. We found that the nuclear density probed by the atomic kaon significantly depends on the kaon orbit. Then, we reexamined the meanings of the observed strengths of one–body and two–body kaon absorption, and investigated the effects to the formation spectra of kaon bound states by in–flight (K−, p) reactions. As a natural conseque...

Recent results are presented for (1) the charge asymmetry in semielectronic kaon decay; (2) the charge radius of the neutral kaon; (3) the decay K 0 L → π 0 π 0 e + e − ; (4) constraints on ρCKM from kaon decays; (5) lepton flavor violation. A few words about future kaon physics work at Fermilab are included.

Kaon physics is an area in which lattice QCD can have an important impact in Phenomenology. I review the recent progress and current status of three particular topics: kaon beta-decay, the kaon B-parameter and the non-leptonic decay of the kaon into two pions.

We study the kaon polarizabilities in the framework of Chiral Perturbation Theory to order p4. For the neutral kaon we find that them vanish and they have the first non-zero contribution to order p6. We also emphasize the theoretical potential of an eventual measurement of the kaon polarizabilities, in particular of the neutral kaon ones. PACS numbers: 14.40.Aq, 13.40.Gp, 13.60.Fz, 12.39.Fe

The variation of kaon mass in dense, charge-neutral baryonic matter at betaequilibrium has been investigated. The baryon interaction has been included by means of nonlinear Walecka model, with and without hyperons and the interaction of kaons with the baryons has been incorporated through the Nelson-Kaplan model. A selfconsistant, one-loop level calculation has been carried out. We find that at...

Within a hadronic transport model we study in detail contributions to kaon yields and momentum spectra from various baryon (resonance)-baryon (resonance) and πN interactions in heavy-ion collisions at beam energies near the free-space kaon production threshold. It is found that the finite lifetime of baryon resonances affects significantly the shape of kaon spectra, and the high energy parts of...
