We introduce a few extensions to the Hyperspherical Harmonics (HH) approach in order to include intrinsic excitations degrees of freedom. To this end we adapt the HH expansion method, usually built up starting from a fixed mass-weighted set of Jacobi coordinates, to the more general case where an arbitrary weighted set of coordinates is adopted. We provide a few results for 3- and 4-body bound state calculations.

Abstract
We introduce a few extensions to the Hyperspherical Harmonics (HH) approach in order to include intrinsic excitations degrees of freedom. To this end we adapt the HH expansion method, usually built up starting from a fixed mass-weighted set of Jacobi coordinates, to the more general case where an arbitrary weighted set of coordinates is adopted. We provide a few results for 3- and 4-body bound state calculations.| File | Dimensione | Formato | |
