Power Counting of Contact-Range Currents in Effective Field Theory
M. Pavón Valderrama, Daniel R. Phillips
We analyze the power counting of two-body currents in nuclear effective field theories (EFTs). We find that the existence of non-perturbative physics at low energies, which is mani…
The magnetic form factor of the deuteron in chiral effective field theory
S. Kolling, E. Epelbaum, D. R. Phillips
We calculate the magnetic form factor of the deuteron up to O(eP^4) in the chiral EFT expansion of the electromagnetic current operator. The two LECs which enter the two-body part…
Precision calculation of the pi^- deuteron scattering length and its impact on threshold pi-N scattering
V. Baru, C. Hanhart, M. Hoferichter +3
We present a calculation of the pi^- d scattering length with an accuracy of a few percent using chiral perturbation theory. For the first time isospin-violating corrections are in…
Subtractive renormalization of the chiral potentials up to next-to-next-to-leading order in higher NN partial waves
C. -J. Yang, Ch. Elster, D. R. Phillips
We develop a subtractive renormalization scheme to evaluate the P-wave NN scattering phase shifts using chiral effective theory potentials. This allows us to consider arbitrarily h…
Deuteron form factors in chiral effective theory: regulator-independent results and the role of two-pion exchange
M. Pavon Valderrama, A. Nogga, E. Ruiz Arriola +1
We evaluate the deuteron charge, quadrupole, and magnetic form factors using wave functions obtained from chiral effective theory (ET) when the potential includes one-pion excha…
How low-energy weak reactions can constrain three-nucleon forces and the neutron-neutron scattering length
A. Gardestig, D. R. Phillips
We show that chiral symmetry and gauge invariance enforce relations between the short-distance physics that occurs in a number of electroweak and pionic reactions on light nuclei.…
