Description
We have evaluated the mesonic decay of the Λ5He hypernucleus by using a Λ wave function generated from the quark cluster model. As a consequence of the ΛN repulsion at short distances we obtain a Λ wave function in the nucleus with a large radius. The smaller overlap with the 4He core with respect to simpler wave functions and the effect of the pion renormalization increase the mesonic width considerably and one obtains a good reproduction of the experimental data.
