Effective Field Theory in Nuclear Physics
The Electromagnetic and Hadronic physics sub-community of nuclear physics held a town hall meeting at Jefferson Lab during November 30 to December 4 of 2000. This is is our combined contribution to the white paper that will result from this meeting. I. THE FUNDAMENTAL SCIENTIFIC QUESTIONS ADDRESSED A fundamental challenge facing the nuclear physics community is the development of a theory that ...
متن کاملEffective Field Theory for Nuclear Physics
I review the current status of the application of effective field theory to nuclear physics, and its present implications for nuclear astrophysics.
متن کاملEffective Field Theory for Nuclear Physics
Low energy data is generally insensitive to the details of interactions at short distance. It is therefore difficult to learn about short range interactions; yet by the same token, complete knowledge of the physics at short distances is not required for an accurate understanding of experiments. Effective field theory exploits this fact. The effects of nonlocal interactions at short distance may...
متن کاملNuclear clusters with Halo Effective Field Theory
At low energies, few-body systems with large scattering length exhibit universal features (universality) that are independent of the interaction details. Some consequences are the existence of a shallow bound state and the Efimov effect1 in the twoand three-body sectors, respectively. These universal properties have a wide range of applications, from particle and nuclear to atomic and molecular...
متن کاملEffective field theory for nuclear matter
We apply the relativistic chiral Lagrangian to the nuclear equation of state. An effective chiral power expansion scheme, which is constructed to work around nuclear saturation density, is presented. The leading and subleading terms are evaluated and are shown to provide an equation of state with excellent saturation properties. Our saturation mechanism is found to probe details of the nuclear ...
