Nucleon-Nucleon Scattering Up to N5LO in Chiral Effective Field Theory
Frontiers in Physics, 2020 During the past few decades a large effort has been made toward describing the NN interaction in the framework of chiral Effective Field Theory (EFT). The main idea is to exploit the symmetries of QCD to obtain an effective theory for low energy nuclear ...

Chromo-Electric Field Energy in Quark Models
Frontiers in Physics, 2019 We study the contribution of the chromo-electric field to the total energy of the hadrons. We analyze the case of quarks considered as extended sources of the field. Specific forms of the interaction potential of the quarks are obtained.

, 1997 This is the final report of a one-year, Laboratory Directed Research and Development (LDRD) project at Los Alamos National Laboratory (LANL). This work completes the determination of the nucleon-nucleon (NN) scattering amplitudes from 485 to 800 MeV. The data set is completed by the publication of two papers. These new data have a precision better than

New Laser Fusion and Its Gain by Intense Laser
Energies, 2010 The feasibility of a new approach of laser fusion in plasma without implosion has been proposed and is discussed using an intense laser. The cross section of the nuclear reaction is increased by enhancing the penetrability of nuclei through the Coulomb ...

Quark Models of the Nucleon–Nucleon Interaction
Frontiers in Physics, 2020 The present paper aims to provide a review of the relevance of quark degrees of freedom in the description of the nucleon-nucleon and, in general, of the baryon-baryon interaction.

Four-nucleon force in chiral effective field theory [PDF]
, 2005 We derive the leading contribution to the four-nucleon force within the framework of chiral effective field theory. It is governed by the exchange of pions and the lowest-order nucleon-nucleon contact interaction and includes effects due to the nonlinear

The nucleon-nucleon interaction [PDF]
Brazilian Journal of Physics, 2004 Recent developements in our understanding of the fundamental nucleon-nucleon interaction are reviewed. Among the topics considered are (1) the so-called high-precision nucleon-nucleon potentials that emerged in the mid 1990s, (2) progress in the microscopic description of the intermediate-range part of the nucleon-nucleon interaction in terms of ...

An optimized chiral nucleon-nucleon interaction at next-to-next-to-leading order [PDF]
, 2013 We optimize the nucleon-nucleon interaction from chiral effective field theory at next-to-next- to-leading order. The resulting new chiral force NNLOopt yields \chi^2 \approx 1 per degree of freedom for laboratory energies below approximately 125 MeV. In

In-medium nucleon-nucleon elastic cross sections determined from nucleon-induced reaction cross sections data [PDF]
Chinese Physics C Vol. 43, No. 4 (2019) 044103, 2015 Within the framework of the improved quantum molecular dynamics model, the medium modifications on the free nucleon-nucleon elastic cross sections are investigated. By using various in-medium nucleon-nucleon elastic cross sections in the model, the nucleon-induced reactions on various targets are simulated, and the excitation functions of reaction ...
