Simplest hypernuclear systems with $A\le5$ and $\Lambda N$ potential

A theoretical analysis of the lightest hypernuclear systems with $A\le 5$ is conducted by means of a multiparticle variational procedure. It is shown that the available experimental data may be described by means of pairwise central spin- and charge-dependent $\Lambda N$ potentials, with possible admixture of the Majorana conponent.
