Particle Mixing and Charge Asymmetric ΛN Forces

الأصل · EN

We calculate the contributions of a particular set of charge asymmetric ΛN interactions to the difference of the separation energies of ⁴ΛHe and ⁴ΛH. We use perturbation theory with four-body variational Monte Carlo wave functions calculated from a Hamiltonian with two- and three-hadron forces. We compare with the data and with an earlier calculation made by one of us which employed a two-body wave function of the Λ-nucleus type.
