Electromagnetic Currents and Magnetic Moments in EFT
S. Pastore, L. Girlanda, R. Schiavilla +2
A two-nucleon potential and consistent electromagnetic currents are derived in chiral effective field theory (EFT) at, respectively, (or NLO) and (or NLO),…
N-d Elastic Scattering Using the Hyperspherical Harmonics Approach with Realistic Local and Non-Local Interactions
L. E. Marcucci, A. Kievsky, L. Girlanda +2
The application of the hyperspherical harmonic approach to the case of the N-d scattering problem below deuteron breakup threshold is described. The nuclear Hamiltonian includes tw…
Neutron-triton elastic scattering
M. Viviani, A. Kievsky, L. Girlanda +1
The Kohn variational principle and the hyperspherical harmonics technique are applied to study n-3H elastic scattering at low energies. In this contribution the first results obtai…
A high-precision variational approach to three- and four-nucleon bound and zero-energy scattering states
A. Kievsky, S. Rosati, M. Viviani +2
The hyperspherical harmonic (HH) method has been widely applied in recent times to the study of the bound states, using the Rayleigh-Ritz variational principle, and of low-energy s…
On a redundancy in the parity-violating 2-nucleon contact Lagrangian
Luca Girlanda
It is shown that the number of independent operators in the nucleon-nucleon parity-violating contact Lagrangian at the leading order in the low-momentum expansion, can be reduced t…
Structure of A=3 Nuclear Systems Using Realistic Hamiltonians
L. E. Marcucci, L. Girlanda, A. Kievsky +2
The structure of A=3 low-energy scattering states is described using the hyperspherical harmonics method with realistic Hamiltonian models, consisting of two- and three-nucleon int…
