Antinucleon–nucleon interaction at low energy: scattering and protonium

E Klempt, F Bradamante, A Martin, JM Richard - Physics Reports, 2002 - Elsevier
We present nucleon–antinucleon scattering experiments performed at the Low Energy
Antiproton Ring (LEAR) of CERN. The data are reviewed and the underlying physics is …

The physics of nucleon-antinucleon annihilation

CB Dover, T Gutsche, M Maruyama… - Progress in Particle and …, 1992 - Elsevier
The nucleon-antinucleon (NN̄) annihilation process provides a fertile testing ground for
microscopic hadron exchange and/or quark models. We review a variety of such …

Precision spectroscopy of light exotic atoms

D Gotta - Progress in Particle and Nuclear Physics, 2004 - Elsevier
The new era in X-ray spectroscopy of exotic atoms is based on high-resolution reflection-
type crystal spectrometers, state-of-the-art X-ray detectors, and sophisticated set-ups to stop …

Antiprotonic-hydrogen atoms

CJ Batty - Reports on Progress in Physics, 1989 - iopscience.iop.org
Experimental studies of antiprotonic-hydrogen atoms have recently made great progress
following the commissioning of the low-energy antiproton facility LEAR at CERN in 1983. At …

One-pion-exchange final-state interaction and the near threshold enhancement in decays

BS Zou, HC Chiang - Physical Review D, 2004 - APS
For the NN system, the one-pion-exchange (OPE) interaction gives the largest attractive
force for NN with an isospin I= 0 and spin S= 0, while a near-threshold enhancement was …
