Nuclear 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 کاملP Renormalizability of Effective Scalar Field Theory
We present a comprehensive discussion of the consistency of the effective quantum field theory of a single Z2 symmetric scalar field. The theory is constructed from a bare Euclidean action which at a scale much greater than the particle’s mass is constrained only by the most basic requirements; stability, finiteness, analyticity, naturalness, and global symmetry. We prove to all orders in pertu...
متن کاملTensor Polarized γ-Deuteron Compton Scattering in Effective Field Theory
The differential cross section for γ-deuteron Compton scattering from a tensor polarized deuteron is computed in an effective field theory. The first non-vanishing contributions to this differential cross section are the interference terms between the leading electric coupling diagrams and the subleading single potential pion exchange diagrams or the subleading magnetic moment coupling diagrams...
متن کاملγ-Deuteron Compton Scattering in Effective Field Theory
The differential cross section for γ-deuteron Compton scattering is computed to next-to-leading order (NLO) in an effective field theory that describes nucleon-nucleon interactions below the pion production threshold. Contributions at NLO include the nucleon isoscalar electric polarizability from its 1/mπ behavior in the chiral limit. The parameter free prediction of the γdeuteron differential ...
