KbarN interaction and Kaons in the nuclear medium
A. Ramos, E. Oset
The s-wave meson-nucleon interaction in the S=-1 sector is studied by means of a coupled-channel Lippmann Schwinger equation, using the lowest order chiral Lagrangian and a cut off…
Binding energy of hypernuclei from realistic YN interactions
I. Vidaña, A. Polls, A. Ramos +1
s- and p-wave single-particle enrgies are obtained for a variety of hypernuclei from the relevant self-energy constructed within the framework of a perturbative many-body a…
The reaction within a one-meson-exchange model
A. Parreño, A. Ramos, N. G. Kelkar +1
With the advent of high precision proton accelerators, such as COSY in Jülich, or with medium energy accelerators like RCNP at Osaka, it may become possible to perform a direct stu…
Weak Decay of Lambda Hypernuclei
E. Oset, A. Ramos
We review recent developments concerning the weak decay of Lambda hypernuclei. New studies covering the mesonic decay channel as well as recent models for the non-mesonic one are d…
Meson-Meson and Meson-Baryon Interactions in a chiral Non-perturbative Approach
E. Oset, J. A. Oller, J. R. Pelaez +1
A qualitative account of the meson-meson and meson-baryon interactions using chiral Lagrangians and the inverse amplitude method in coupled channels is done. The method, imposing e…
Non-perturbative chiral approach to Kp -->gamma Y reactions
T. -S. H. Lee, J. A. Oller, E. Oset +1
A recently developed nonperturbative chiral approach to describe the S=-1 meson-baryon reactions has been extended to investigate the near threshold reactions.…
