Particle Mixing and Charge Asymmetric ΛN Forces
S. A. Coon, H. K. Han, J. Carlson, B. F. Gibson
Abstract
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.
