Achim Schwenk: Neutrinos rates from chiral effective field theory

Achim talked about how to calculate nuclear reaction rates determined by spin relaxation time. This method allows to calculate scattering of neutrinos from one or two nucleons.
The spin response is embedded in the dynamical structure factor of the nucleons. The nucleon interactions are described by chiral effective field theory. I found very interesting his comparison of the chiral EFT and different interactions, including the V- k-low potential, and that they reproduced similar spin relaxation rates at low density. At high density chiral 3n interactions suppresses this rate.
