Deuteron electromagnetic properties and the viability of effective field theory methods in the two-nucleon system
D. R. Phillips, T. D. Cohen
The central tenet of effective theory is that the details of short-distance physics will not have a significant impact on low-energy observables. Here we perform an analysis of ele…
The pion photoproduction in the Δ(1232) region
Chung Wen Kao, Thomas D. Cohen
We investigate the pion photoproduction in the Δ(1232) region in the framework of an effective Lagrangian including pions, nulceon and Δ(1232). We work to third order in a small sc…
Regularization and renormalization in effective field theories of the nucleon-nucleon interaction
D. R. Phillips, S. R. Beane, T. D. Cohen
Some form of nonperturbative regularization is necessary if effective field theory treatments of the NN interaction are to yield finite answers. We discuss various regularization s…
The potential of effective field theory in NN scattering
S. R. Beane, T. D. Cohen, D. R. Phillips
We study an effective field theory of interacting nucleons at distances much greater than the pion's Compton wavelength. In this regime the NN potential is conjectured to be the su…
Short-range interactions in an effective field theory approach for nucleon-nucleon scattering
K. A. Scaldeferri, D. R. Phillips, C. -W. Kao +1
We investigate in detail the effect of making the range of the ``contact'' interaction used in effective field theory (EFT) calculations of NN scattering finite. This is done in bo…
Rho-Omega Mixing Off Shell and Charge Symmetry Breaking In the N-N Potential
Thomas D. Cohen, Gerald A. Miller
The role of the off-shell dependence of mixing in the charge symmetry breaking nucleon-nucleon potential is discussed. It is shown that models describing the off-shell depend…
