Nucleon-Nucleon Scattering from Fully Dynamical Lattice QCD [PDF]
We present results of the first fully-dynamical lattice QCD determination of nucleon-nucleon scattering lengths in the 1S0 channel and 3S1-3D1 coupled channels. The calculations are performed with domain-wall valence quarks on the MILC staggered configurations with lattice spacing of b=0.125 fm in the isospin-symmetric limit, and in the absence of ...

Theory of Low-Energy Nucleon-Nucleon Scattering [PDF]
The two-nucleon problem is discussed from the standpoint of the double dispersion relations. The analytic structure of partial wave amplitudes is completely analyzed. This is greatly facilitated by the use of the Jacob-Wick helicity amplitudes. The program of generating a set of dynamical equations by use of the unitarity condition is carried out.

Nucleon-nucleon scattering from effective field theory [PDF]
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 been used previously; it is no a chiral expansion in powers of the pion mass.

Helium range viability for online range probing in mixed carbon-helium beams. [PDF]
Abstract BackgroundRecently, mixed carbon–helium beams were proposed for range verification in carbon ion therapy: helium, with three times the range of carbon, serves as an online range probe and is mixed into a therapeutic carbon beam. PurposeTreatment monitoring is of special interest for lung cancer therapy; however, the helium range might not ...

1S0 nucleon-nucleon scattering in the modified Weinberg approach [PDF]
Nucleon-nucleon scattering in the 1S0 partial wave is considered in chiral effective field theory within the renormalizable formulation of a previous work (Phys. Lett. B 716, 338 (2012)) beyond the leading-order approximation.

Peripheral nucleon-nucleon scattering at fifth order of chiral perturbation theory [PDF]
We present the two- and three-pion exchange contributions to the nucleon-nucleon interaction which occur at next-to-next-to-next-to-next-to-leading order (N4LO, fifth order) of chiral effective field theory, and calculate nucleon-nucleon scattering in ...

More on Heisenberg’s model for high energy nucleon-nucleon scattering [PDF]
We revisit Heisenberg's model for nucleon-nucleon scattering which admits a saturation of the Froissart bound. We examine its uniqueness, and find that up to certain natural generalizations, it is the only action that saturates the bound. We find that we

Nucleon-nucleon scattering from distillation
We report an ongoing analysis of nucleon-nucleon scattering based on finite-volume spectroscopy. The calculation is performed using the distillation method on eight lattice ensembles at the SU(3)-symmetric point with $m_\pi=m_K\approx 420$ MeV generated by CLS, covering a range of lattice spacings and volumes and previously used to study the $H ...

The phase-functions method and full cross-section of nucleon–nucleon scattering [PDF]
A known phase-functions method (PFM) has been considered for calculation of a single-channel nucleon–nucleon scattering. The following phase shifts of a nucleon–nucleon scattering have been calculated numerically using the phase-functions method:nn(1S 0-,
