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…
Neutron spin rotation in \vec{n}-d scattering
R. Schiavilla, M. Viviani, L. Girlanda +2
The neutron spin rotation induced by parity-violating (PV) components in the nucleon-nucleon potential is studied in \vec{n}-d scattering at zero energy. Results are obtained corre…
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…
