EPJ A - A new technique for simultaneous measurement of neutron-induced capture and fission reactions

The accurate knowledge of (n,gamma) neutron-capture cross-sections for fissile isotopes is highly relevant for next-generation applications of nuclear technology. However, accurate measurements are difficult due to the gamma-ray background generated in competing (n,f) fission reactions. Scientists at the n_TOF facility at CERN have developed a new experimental setup that is capable of simultaneously measuring and identifying the capture and fission reactions.


EPJ A - Vector Correlators in Lattice QCD: Methods and Applications

Vacuum polarisation, the modification of the photon propagator due to virtual electron-positron pairs, is one of the first quantum loop corrections encountered in field theory. In both QED and QCD it causes the running of the appropriate fine structure constant as the physical scale is varied, and also corrects the magnetic moments of electrons and muons from the value 2 predicted by the Dirac equation.


EPJ A - The Similarity Renormalization Group for Three-Body Interactions in One Dimension

One important message that has emerged from developments of effective field theories and effective Hamiltonians for nuclear physics is that many-body forces are inevitable whenever degrees of freedom are eliminated. At the same time, first-principles calculations have shown that two-body forces alone are not able to give an accurate account of the energies of light nuclei and the saturation of nuclear matter. Three- (and possibly more-) body forces are thus essential in low-energy nuclear physics.


EPJ A – Validating Aspects of the Strong-Coupling Regime of QCD

EPJ A – Validating Aspects of the Strong-Coupling Regime of QCD

A key to our understanding of Quantum Chromodynamics (QCD) in the strong regime is our ability to reproduce the hadronic excitation spectrum. Up to now, and due to their limited predictive power, quark models forecast of this spectrum at high excitation energies is unsatisfactory and is dubbed ``the missing resonances problem”. To explore the high excitation energies in the hadron spectrum production or scattering of heavier mesons from a nucleon target is essential.


EPJ A broadens its scope in heavy ion physics

EPJ A broadens its scope in heavy ion physics by merging with the Acta Physica Hungarica A - Heavy Ion Physics (APH A) as of January 1st, 2007. APH A, a well respected journal in the field has emerged from the Acta Physics Hungarica, initially covering all areas of physics, in the 1990s.
