Neutrino mean free path and in - medium nuclear interaction
Neutrinos produced during the collapse of a massive star are trapped in a nuclear medium (the proto-neutron star). Typically, neutrino energies (10-100 MeV) are of the order of nuclear giant resonances energies. Hence, neutrino propagation is modified by the possibility of coherent scattering on nucleons. We have compared the predictions of different nuclear interaction models. It turns out tha...
متن کاملIsovector nuclear spin-orbit interaction from chiral pion-nucleon dynamics
Using the two-loop approximation of chiral perturbation theory, we calculate the momentum and density dependent isovector nuclear spin-orbit strength Vls(p, kf ). This quantity is derived from the spin-dependent part of the interaction energy Σspin = i 2 ~σ · (~q × ~ p )[Uls(p, kf ) − Vls(p, kf )τ3δ] of a nucleon scattering off weakly inhomogeneous isospinasymmetric nuclear matter. We find that...

Using the two-loop approximation of chiral perturbation theory, we calculate the momentum and density dependent nuclear spin-orbit strength Uls(p, kf ). This quantity is derived from the spin-dependent part of the interaction energy Σspin = i 2 ~σ ·(~q×~p )Uls(p, kf ) of a nucleon scattering off weakly inhomogeneous isospin symmetric nuclear matter. We find that iterated 1π-exchange generates a...
متن کاملComments on spin-orbit interaction of anyons
The coupling of non-relativistic anyons (called exotic particles) to an electromagnetic field is considered. Anomalous coupling is introduced by adding a spin-orbit term to the Lagrangian. Alternatively, one has two Hamiltonian structures, obtained by either adding the anomalous term to the Hamiltonian, or by redefining the mass and the NC parameter. The model can also be derived from its relat...
متن کاملspin–orbit interaction
We have measured the hyperfine structure of mutually perturbing rovibrational levels of the 1sbd P0 and 2sAd S states of the NaK molecule, using the perturbation-facilitated optical-optical double resonance method with copropagating lasers. The unperturbed 1sbd P0 levels are split into four hyperfine components by the Fermi contact interaction bFI ·S. Mixing between the 1sbd P0 and 2sAd S level...
