Photoproduction of the Λ(1405) on the Proton and Nuclei
We study the γp → K+Λ(1405) reaction at energies close to threshold using a chiral unitary model where the resonance is generated dynamically from Kp interaction with other channels constructed from the octets of baryons and mesons. Predictions are made for cross sections into several channels and it is shown that the detection of the K+ is sufficient to determine the shape and strength of the ...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

متن کاملPhotoproduction of K ∗ for the study of Λ(1405)
Photo-induced K * vector meson production is investigated for the study of the Λ(1405) resonance. This reaction is particularly suited to the isolation of the second pole in the Λ(1405) region which couples dominantly to the ¯ KN channel. We obtain the mass distribution of the Λ(1405) which peaks at 1420 MeV, and differs from the nominal one. Combined with several other reactions, this detailed...
متن کاملThe 1405 MeV Lambda Resonance in Full-QCD
The negative-parity ground state of the Λ baryon lies surprisingly low in mass. At 1405.1MeV, it lies lower than the negative-parity ground state nucleon, even though it has a valence strange quark. Using the PACS-CS (2+ 1)-flavour full-QCD ensembles available through the ILDG, we employ a variational analysis using source and sink smearing to investigate the low-energy, odd-parity spectrum of ...
