[en] We have compared various models of the K- optical potential and tested them in fits to the available K- atomic data. The quality of the fits is satisfactory for the both relatively 'shallow' optical potentials derived from chirally motivated models and for the 'deep' potentials based on phenomenological analyses. We show that (Kstop-,τ) hypernuclear production rates are very sensitive to the details of the kaonic bound state wave function. The reaction is thus suitable to distinguish between K- optical potentials

[en] Radiative capture of the K- on the deuteron is examined as a reaction for the measurement of the Λ-neutron scattering lengths. It is shown that a measurement of the deviation of the vector deuteron polarization asymmetry from -1 provides a direct determination of the difference of the singlet and triplet scattering lengths.

[en] A description of the techniques used in FINUDA to perform, by means of global fits, the analysis of some YN (hyperon-nucleon) spectra is reported. The study of the features of many experimental spectra and how they can be decomposed by contributions of Quasi-Free (QF) background reactions is a fundamental issue to achieve a good and reliable description of the K"−2N→YN absorptions

[en] Λ(1405) is considered as a superposition of two resonances instead of a simple bound state of the kaon and proton. Within the framework of the Brueckner-Hartree-Fock(BHF) theory, we have investigated the K-bar nuclear systems (S=-1), especially K-pp and K-pnn(T=1). The binding energy BK- is 23 MeV (3 MeV) and the width Γ is 62 MeV (56 MeV) for K-pp(K-pnn(T= 1)). (authors)

[en] We have performed an experiment to search deeply bound K-ppn system. We finished data taking at the end of October 2002. We are presently analyzing the data and describe current status, focusing on stopped K- event selection and tracking of secondary particles. (author)
