Electromagnetic Production of the Hypertriton
نویسنده
چکیده
Kaon photoproduction on 3He, γ + 3He −→ K+ + ΛH, is studied in the framework of the impulse approximation. Realistic 3He wave functions obtained as solutions of Faddeev equations with the Reid soft-core potential are used along with a simple ΛH wave function. Results are compared for several elementary operator models, which can successfully describe the elementary kaon production off the proton up to a photon lab energy of k = 2.2 GeV. It is found that the corresponding cross sections are small, of the order of 1 nb. It is also shown that the influence of Fermi motion is important, while the effect of different off-shell assumptions on the cross section is not too significant.

Threshold Production of the Hypertriton
The cross section for threshold production of the hypertriton in the reaction pd → ΛHK + is calculated in a two-step model and compared to the break-up process pd → dΛK. The latter process is shown to be dominant already at 2 MeV above threshold. The amplitude squared at threshold for the pd→ ΛHK + reaction is |f | = 1.0 nb/sr. e-mail: [email protected]
متن کاملHypertriton Electric Polarizability
A rigorous formalism for determining the electric dipole polarizability of a threehadron bound complex in the case that the system has only one bound (ground) state has been elaborated. On its basis, by applying a model wave function that takes into account specific features of the structure of the lightest hypernucleus and using the known low-energy experimental data for the p − n and Λ − d sy...

متن کاملRegularized zero-range model and an application to the triton and the hypertriton
We examine the regularized zero-range model in an application to three-fermion systems – the triton and the hypertriton. We consider bound states and low-energy neutron-deuteron and lambda-deuteron scattering. The model is shown to provide an adequate quantitative description of these system on a par with finite-range potential models. The well known correlation between the doublet nd scatterin...
متن کاملDesign and Production of a Pneumatic Moving Exciter for Determination of Vibration Behavior of Structures in Variable Frequencies
Determination and analysis of vibration behavior of structures for at least first few natural frequencies and mode shapes needs several sensors to be connected at different non node points and exciting the structure at one point. Other method for determination of first few mode shapes is to excite several points of the structure at once and sensing the response from one point. Both methods nee...
