Triton and Neutron-Deuteron Scattering up to Next-to-Leading Order in Chiral EFT
Young-Ho Song, Rimantas Lazauskas, U. van Kolck
Determination of the proper power-counting scheme is an important issue for the systematic application of Chiral Effective Field Theory in nuclear physics. We analyze the cutoff de…
Power Counting in Peripheral Partial Waves: The Singlet Channels
M. Pavón Valderrama, M. Sánchez Sánchez, C. -J. Yang +3
We analyze the power counting of the peripheral singlet partial waves in nucleon-nucleon scattering. In agreement with conventional wisdom, we find that pion exchanges are perturba…
Nuclear Physics Around the Unitarity Limit
Sebastian König, Harald W. Grießhammer, H. -W. Hammer +1
We argue that many features of the structure of nuclei emerge from a strictly perturbative expansion around the unitarity limit, where the two-nucleon S waves have bound states at…
Effective Field Theory for Few-Boson Systems
Betzalel Bazak, Moti Eliyahu, Ubirajara van Kolck
We study universal bosonic few-body systems within the framework of effective field theory at leading order (LO). We calculate binding energies of systems of up to six particles an…
