A Comprehensive Study of the Three- and Four-Neutron Systems at Low Energies

Michael D. Higgins, Chris H. Greene, Alejandro Kievsky +1

This work presents further analysis of the three- and four-neutron systems in the low energy regime using adiabatic hyperspherical methods. In our previous Phys. Rev. Lett. article…

Gaussian characterization of the unitary window for : bound, scattering and virtual states

A. Deltuva. A. Kievsky, M. Gattobigio, M. Viviani

The three-body system inside the unitary window is studied for three equal bosons and three equal fermions having spin-isospin symmetry. We perform a gaussian characterizatio…

Unitary ambiguity of NN contact interactions and the 3N force

L. Girlanda, A. Kievsky, L. E. Marcucci +1

We identify a redundancy between two- and three-nucleon contact interactions at the fourth and fifth order of the chiral expansion respectively. In particular we show that tensor-t…

Calculation of the Li ground state within the hyperspherical harmonic basis

Alex Gnech, Michele Viviani, Laura Elisa Marcucci

We have studied the solution of the six-nucleon bound state problem using the hyperspherical harmonic (HH) approach. For this study we have considered only two-body nuclear forces.…

Study of H, He, H, and He scattering with the HH method

M. Viviani, L. Girlanda, A. Kievsky +1

The H, He, H, and He elastic and charge exchange reactions at low energies are studied by means of the hyperspherical harmonic method. The considere…

Parity- and time-reversal-violating nuclear forces

J. de Vries, E. Epelbaum, L. Girlanda +3

Parity-violating and time-reversal conserving (PVTC) and parity-violating and time-reversal-violating (PVTV) forces in nuclei form only a tiny component of the total interaction be…
