Precision nucleon-nucleon potential at fifth order in the chiral expansion [PDF]

open access: yes, 2014
We present a nucleon-nucleon potential at fifth order in chiral effective field theory. We find a substantial improvement in the description of nucleon-nucleon phase shifts as compared to the fourth-order results of Ref. [E. Epelbaum, H. Krebs, U.-G. Mei{

Cluster emission and phase transition behaviours in nuclear disassembly [PDF]

open access: yes, 2001
The features of the emissions of light particles (LP), charged particles (CP), intermediate mass fragments (IMF) and the largest fragment (MAX) are investigated for $^{129}Xe$ as functions of temperature and 'freeze-out' density in the frameworks of the ...

Effective Field Theory For Nuclei, Dense Matter And The Cheshire Cat [PDF]

open access: yes, 1999
In this talk I discuss three related topics based on some of the recent developments in hadron and nuclear physics: one, effective field theory approach to two-nucleon systems; two, an explanation of the flavor singlet axial charge in the proton (i.e ...

Lattice Simulations for Light Nuclei: Chiral Effective Field Theory at Leading Order [PDF]

open access: yes, 2006
We discuss lattice simulations of light nuclei at leading order in chiral effective field theory. Using lattice pion fields and auxiliary fields, we include the physics of instantaneous one-pion exchange and the leading-order S-wave contact interactions.

Nucleon-Nucleon Interaction: A Typical/Concise Review [PDF]

open access: yes, 2007
Nearly a recent century of work is divided to Nucleon-Nucleon (NN) interaction issue. We review some overall perspectives of NN interaction with a brief discussion about deuteron, general structure and symmetries of NN Lagrangian as well as equations of ...

On a Missed Mechanism of Dielectron Production in Nucleon-Nucleon Collisions

open access: yes, 2010
We examine a new mechanism of $e^+e^-$ pair production in $NN$ collisions associated with the $NN$-decoupled dibaryon $d^\star_1$(1956) formation in the process $NN \to \gamma^\star d^\star_1$, where $\gamma^\star$ is the virtual photon which converts ...

Neutrino-nucleus reactions in the energy range 1-100 MeV [PDF]

open access: yes, 2006
We review some salient aspects of calculations of the neutrino-nucleus reaction cross sections in the low energy range (1-100 MeV).Comment: 6 pages:Invited talk at NuInt05 (Fourth International Workshop on Neutrino- Nucleus Interactions in the Few-GeV ...

Effective Field Theory and Finite Density Systems

open access: yes, 2008
This review gives an overview of effective field theory (EFT) as applied at finite density, with a focus on nuclear many-body systems. Uniform systems with short-range interactions illustrate the ingredients and virtues of many-body EFT and then the ...

Perturbative Effective Field Theory at Finite Density [PDF]

open access: yes, 1999
An accurate description of nuclear matter starting from free-space nuclear forces has been an elusive goal. The complexity of the system makes approximations inevitable, so the challenge is to find a consistent truncation scheme with controlled errors ...
