“…Note that the consistency of the cross sections in the very small kaon-angle region with the results of the SL model ( Fig. 3) and the fact that these cross sections are dominated by the spin-flip part of the amplitude could predetermine the new models for successful predictions of the cross sections in the production of the hypernuclei, like the Saclay-Lyon model [3,44].…”

Kaon photoproduction on the proton is studied in the resonance region using an isobar model. The higher-spin nucleon (3/2 and 5/2) and hyperon (3/2) resonances were included in the model utilizing the consistent formalism by Pascalutsa, and they were found to play an important role in data description. The spin-1/2 and spin-3/2 hyperon resonances in combination with the Born terms contribute significantly to the background part of the amplitude. Various forms of the hadron form factor were considered in the construction, and the dipole and multidipole forms were selected as those most suitable for the data description. Model parameters were fitted to new experimental data from CLAS, LEPS, and GRAAL collaborations and two versions of the model, BS1 and BS2, were chosen. Both models provide a good overall description of the data for the center-of-mass energies from the threshold up to 2.4 GeV. Predicted cross sections of the models at very small kaon angles being consistent with results of the Saclay-Lyon model indicate that the models could be also successful in predicting the hypernucleus production cross sections. Although kaon photoproduction takes place in the third-resonance region with many resonant states, the total number of included resonances, 15 and 16, is quite moderate and it is comparable with numbers of resonances in other models. The set of chosen nucleon resonances overlaps well with the set of the most probable contributing states determined in the Bayesian analysis with the Regge-plus-resonance model. Particularly, we confirm that the missing resonances P13(1900) and D13(1875) do play an important role in the description of data. However, the spin-1/2 state P11(1880) included in the Bayesian analysis was replaced in our analysis with the near-mass spin-5/2 state N * (1860), recently considered by the Particle Data Group.

“…The experimental BE of the Λ state is 11.37 MeV (see, e.g., Refs. [14,16,15]). Since the experimental values of the BE for the Ξ − bound state is still unknown, we have adopted in our search procedure the corresponding value predicted in the latest version of the quark-meson coupling (QMC) model [25] ) is about half of the Λ-nucleus interaction (V Λ ).…”

“…The electromagnetic probes like photons and electrons can also be used for this purpose. Although, the stopped as well as in-flight (K − , π − ) [3,7] and (π + , K + ) [2,3,7] reactions have been most extensively used in the experimental investigations of their production, the feasibility of producing them via the (p, K + ) [8,9,10], (γ, K + ) [11,12,13] and (e, e ′ K + ) [14,15,16,17,18,19] reactions has also been demonstrated in the recent years. The (K − , K + ) reaction is one of the most promising ways of studying the S = −2 Ξ hypernuclei becuase it leads to the transfer of two units of both charge and strangeness to the target nucleus.…”

We present an overview of a fully covariant formulation for describing the production of strangeness -1 and -2 hypernuclei using probes of different kinds. This theory is based on an effective Lagrangian picture and it focuses on production amplitudes that are described via creation, propagation and decay into relevant channel of intermediate baryonic resonance states in the initial collision of the projectile with one of the target nucleons. The bound state nucleon and hyperon wave functions are obtained by solving the Dirac equation with appropriate scalar and vector potentials. Specific examples are discussed for reactions which are of interest to current and future experiments on the hypernuclear production.

A systematic study on the probability for the emission of He 4 and C 14 cluster from hyper Ac 234 207− Λ and non-strange normal Ac 234 207− nuclei are performed for the first time using our fission model, the Coulomb and proximity potential model (CPPM). The predicted half lives show that hyper Ac 234 207− Λ nuclei are unstable against He 4 emission and C 14 emission from hyperAc 228 217− Λ are favorable for measurement. Our study also show that hyper PACS. 23.60. +e Alpha decay -23.70. +j Heavy particle decay -21.80.+a Hypernuclei
