Double Λ Hypernuclei and the Λ-λ Interaction. *
We approximate the double Λ hypernuclei by systems composed by two interacting Λ’s moving in the mean field potential created by the nuclear cores. The Λ-core potentials are adjusted to reproduce the binding energies of the corresponding single Λ hypernuclei [1]. A σ-ω meson exchange potential [2] is used for the Λ-Λ interaction. We apply both the Hartree-Fock (HF) and variational approximation...

In this paper we present an algorithm for pricing barrier options in one-dimensional Markov models. The approach rests on the construction of an approximating continuous-time Markov chain that closely follows the dynamics of the given Markov model. We illustrate the method by implementing it for a range of models, including a local Lévy process and a local volatility jump-diffusion. We also pro...
متن کاملRare Λ b → Λ l + l − Decays with Polarized Λ
We investigate the rare baryonic exclusive decays of Λb → Λll (l = e, μ, τ) with polarized Λ. Under the approximation of the heavy quark effective theory (HQET), in the standard model we derive the differential decay rates and various polarization asymmetries by including lepton mass effects. We find that with the long-distance effects the decay branching ratios are 5.3× 10 for Λb → Λll (l = e,...
متن کاملPhotoproduction 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 کاملWeak Transition in Double-Λ Hypernuclei
We calculate the ΛΛ → Y N transition rate of 6 ΛΛHe by the hybrid picture, the π and K exchanges plus the direct quark processes. It is found that the hyperon-induced decay is weaker than the nucleon-induced decay, but the former may reveal the short-range mechanism of the weak transition and also give a clear signal of the strong ∆I = 3/2 transition. The ΛΛ → YN transition in double-Λ hypernuc...
