Photoproduction of the Lambda(1405) on the proton and nuclei
J. C. Nacher, E. Oset, H. Toki +1
We study the gamma p ---> K^+ Lambda(1405) reaction at energies close to threshold using a chiral unitary model where the resonance is generated dynamically from K^-p interaction w…
Hadronic Vacuum Polarization and the Lamb Shift
J. L. Friar, J. Martorell, D. W. L. Sprung
Recent improvements in the determination of the running of the fine-structure constant also allow an update of the hadronic vacuum-polarization contribution to the Lamb shift. We f…
Nuclear surface properties in relativistic effective field theory
M. Del Estal, M. Centelles, X. Viñas
We perform Hartree calculations of symmetric and asymmetric semi-infinite nuclear matter in the framework of relativistic models based on effective hadronic field theories as recen…
The weak strangeness production reaction in a one-boson-exchange model
A. Parreño, A. Ramos, N. G. Kelkar +1
The weak production of Lambdas in nucleon-nucleon scattering is studied in a meson-exchange framework. The weak transition operator for the reaction is identical to a…
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…
Isospin symmetry breaking nucleon-nucleon potentials and nuclear structure
H. Muether, A. Polls, R. Machleidt
Modern nucleon-nucleon (NN) potentials, which accurately fit the nucleon-nucleon scattering phase shifts, contain terms which break isospin symmetry. The effects of these symmetry…
Hyperon properties in finite nuclei using realistic interactions
I. Vidaña, A. Polls, A. Ramos +1
Single-particle energies of the and hyperons are obtained from the relevant self-energies. The latter are constructed within the framework of a perturbative many-body appro…
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.…
Analysis of exchange terms in a projected ERPA Theory applied to the quasi-elastic (e,e') reaction
E. Bauer, A. Polls, A. Ramos
A systematic study of the influence of exchange terms in the longitudinal and transverse nuclear response to quasi-elastic (e,e') reactions is presented. The study is performed wit…
