Calculation of the A=6 bound states within the hyperspherical harmonic basis*

We present some recent results of the application of the Hyperspherical Harmonic (HH) approach to A=6 nuclei. The use of a new computational approach permitted the extension of the HH method, successfully used by the Pisa in the few-body system context, to study larger systems. We will shortly review some of the technical improvements and then we will show the results for the spectra of the A=6 nuclei computed with modern SRG evolved two-body chiral interactions. Moreover, we will present also some preliminary study where the three-body intractions are added. Finally, we will show a first application of the HH approach technique that we are studying for solving scattering states for A>4. In this presentation, we will try to demonstrate that the HH appproach can reach the same level of accuracy obtained by the mostly used No-Core-Shell-Model method also beyond the few-body sector.
