Partially-Quenched Nucleon-Nucleon Scattering

Nucleon-nucleon scattering is studied to next-to-leading order in a partially-quenched extension of an effective field theory used to describe multinucleon systems in QCD. The partially-quenched nucleon-nucleon amplitudes will play an important role in relating lattice simulations of the two-nucleon sector to nature.

Nucleon–nucleon and Pion–nucleon Potentials from Phase Shifts Using Quantum Inversion

NN and πN partial wave radial potentials have been generated using the latest SM94–VPI(NN) and FA93–VPI(πN) phase shifts. The potentials are used to determine the deuteron properties and to compute the H and He binding energies. The ε1 mixing angles of SM94–VPI and NY93–Nijmegen differ significantly and inversion potentials yield a Pd of 6.37% and 5.78%, respectively. Under–binding of H and He ...

Phase-shifts determination for nucleon-nucleon scattering using velocity-dependent potentials

The S-wave time-independent Schrödinger equation with an isotropic velocity-dependent potential is considered .We have used perturbation theory to calculate the scattering phase shifts when the energy is changed by a small amount ∆E from an arbitrary unperturbed value E0. The validity of our results were tested by comparing the perturbed phase shifts to those obtained exactly by solving Schrödi...

Reduction of neutrino - nucleon scattering rate by nucleon - nucleon collisions

The collapse-driven supernova is supposed to be an outcome of gravitational collapse of a massive star ∼ 8M at the end of its evolution. Although more than 60 years have passed since the original idea by Baade and Zwicky [1,2], and the detection of neutrinos from SN1987A [3,4] confirmed that our scenario is correct on the whole, we have not yet figured out how this phenomenon occurs. These days...

Effective chiral theory of nucleon-nucleon scattering

We present a new chiral expansion scheme for the nucleon-nucleon scattering amplitude which preserves unitarity exactly. Our effective field theory builds on the power counting rules for 2-nucleon reducible diagrams proposed in [1]. We evaluate the leading order terms of the isospin one scattering amplitude and elaborate in detail on the S0 phase shift. Our chiral description of the S0phase shi...
