Covariant spectator theory of np scattering: Deuteron quadrupole moment
Abstract
The deuteron quadrupole moment is calculated using two CST model wave functions obtained from the 2007 high precision fits to np scattering data. Included in the calculation are a new class of isoscalar np interaction currents automatically generated by the nuclear force model used in these fits. The prediction for model WJC1, with larger relativistic Pstate components, is 2.5% smaller that the experiential result, in common with the inability of models prior to 2014 to predict this important quantity. However, model WJC2, with very small Pstate components, gives agreement to better than 1%, similar to the results obtained recently from _{X}EFT predictions to order N ^{3}LO.

Covariant spectator theory of $np$ scattering:\\ Effective range expansions and relativistic deuteron wave functions
We present the effective range expansions for the 1S0 and 3S1 scattering phase shifts, and the relativistic deuteron wave functions that accompany our recent high precision fits (with \chi^2/N{data} \simeq 1) to the 2007 world np data below 350 MeV. The wave functions are expanded in a series of analytical functions (with the correct asymptotic behavior at both large and small arguments) that can be Fouriertransformed from momentum to coordinate space and are convenient to use in any application. A fortran subroutine to compute these wave functions can be obtained from the authors. 
Covariant spectator theory of np scattering: Effective range expansions and relativistic deuteron wave functions
We present the effective range expansions for the {sup 1}S{sub 0} and {sup 3}S{sub 1} scattering phase shifts, and the relativistic deuteron wave functions that accompany our recent high precision fits (with {chi}{sup 2}/N{sub data{approx_equal}}1) to the 2007 world np data below 350 MeV. The wave functions are expanded in a series of analytical functions (with the correct asymptotic behavior at both large and small arguments) that can be Fouriertransformed from momentum to coordinate space and are convenient to use in any application.

Covariant spectator theory of $np$ scattering:\\ Phase shifts obtained from precision fits to data below 350 MeV
Using the covariant spectator theory (CST), we present two one boson exchange kernels that have been successfully adjusted to fit the 2007 world $np$ data (containing 3788 data) below 350 MeV. One model (which we designate WJC1) has 27 parameters and fits with a chi2/N = 1.06. The other model (designated WJC2) has only 15 parameters and fits with a chi2/N = 1.12. Both of these models also reproduce the experimental triton binding energy without introducing additional irreducible threenucleon forces. One result of this work is a new phase shift analysis, updated for all data until 2006, which is usefulmore »
