n + p -> d + gamma in Effective Field Theory
Martin J. Savage, Kevin A. Scaldeferri, Mark B. Wise
The radiative capture process n+p-> d+gamma provides clear evidence for meson exchange currents in nuclear physics. We compute this process at low energies using a recently develop…
An Effective Field Theory Calculation of the Parity Violating Asymmetry in n+p -> d+gamma
David B. Kaplan, Martin J. Savage, Roxanne P. Springer +1
Weak interactions are expected to induce a parity violating pion-nucleon coupling, h_{πNN}^{(1)}. This coupling should be measurable in a proposed experiment to study the parity vi…
A Perturbative Calculation of the Electromagnetic Form Factors of the Deuteron
David B. Kaplan, Martin J. Savage, Mark B. Wise
Making use of the effective field theory expansion recently developed by the authors, we compute the electromagnetic form factors of the deuteron analytically to next-to-leading or…
A New Expansion for Nucleon-Nucleon Interactions
David B. Kaplan, Martin J. Savage, Mark B. Wise
We introduce a new and well defined power counting for the effective field theory describing nucleon-nucleon interactions. Because of the large NN scattering lengths it differs fro…
Two-Nucleon Systems from Effective Field Theory
David B. Kaplan, Martin J. Savage, Mark B. Wise
We elaborate on a new technique for computing properties of nucleon-nucleon interactions in terms of an effective field theory derived from low energy NN scattering data. Details o…
Nucleon-Nucleon Scattering from Effective Field Theory
David B. Kaplan, Martin J. Savage, Mark B. Wise
We perform a nonperturbative calculation of the 1S0 NN scattering amplitude using an effective field theory (EFT) expansion. The expansion we advocate is a modification of what has…
