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 …

Abstract The Antiproton Decelerator (AD) facility of CERN began operation in 1999 to serve
experiments for studies of CPT invariance by precision laser and microwave spectroscopy of …

The threshold p¯ p peak in BES data for J/Ψ→ γp¯ p may be fitted as a cusp. It arises from
the well-known threshold peak in p¯ p elastic scattering due to annihilation. Several similar …

We propose a novel antiparticle detector. The gaseous antiparticle spectrometer (GAPS)
effects particle identification through the characteristic X-rays emitted by antiparticles when …

A bstract Results for the antinucleon-nucleon\(\left (\overline {N}\; N\right)\) interaction
obtained at next-to-next-to-next-to-leading order in chiral effective field theory (EFT) are …

Some experimental limits on the annihilation cross sections σ ann of antiprotons on carbon,
palladium, and platinum targets were determined at the previously unexplored kinetic …

We present a simple interpretation of the recently observed near-threshold proton-antiproton
enhancement. It is described by a set of low-energy parameters deduced from the analysis …

In this paper, we study the structure around the pp¯ threshold that appears in η′ π+ π-, 3
(π+ π-) and KS 0 KS 0 η invariant mass spectra in the processes of relevant J/ψ radiative …

We have recently highlighted the presence of a periodically oscillating 10% modulation in
the BABAR Collaboration data on the proton timelike form factors, expressing the deviations …

We simulate the deceleration and transmission of antiprotons with keV-scale kinetic
energies through polymer foils using a molecular dynamics approach, which includes a …
