CPT and Lorentz symmetry tests with hydrogen using a novel in-beam hyperfine spectroscopy method applicable to antihydrogen experiments

Lilian Nowak, Chloe Malbrunot, Martin C. Simon +8

We present a Rabi-type measurement of two ground-state hydrogen hyperfine transitions performed in two opposite external magnetic field directions. This puts first constraints at t…

Coupled Channel Analysis of $p ˉ p \to π^{0} π^{0} η$ , $π^{0} η η$ and $K^{+} K^{-} π^{0}$ at 900 $M e V / c$ and of $π π$ -Scattering Data

Crystal Barrel Collaboration, M. Albrecht, C. Amsler +12

A partial wave analysis of antiproton-proton annihilation data in flight at 900 $M e V / c$ into $π^{0} π^{0} η$ , $π^{0} η η$ and $K^{+} K^{-} π^{0}$ is presented. The data were taken at LEAR by t…

Measurement of the $π K$ atom lifetime and the $π K$ scattering length

DIRAC Collaboration, B. Adeva, L. Afanasyev +62

After having announced the statistically significant observation (5.6~ $σ$ ) of the new exotic $π K$ atom, the DIRAC experiment at the CERN proton synchrotron presents the measurement…

Measurement of antiproton annihilation on Cu, Ag and Au with emulsion films

S. Aghion, C. Amsler, A. Ariga +69

The characteristics of low energy antiproton annihilations on nuclei (e.g. hadronization and product multiplicities) are not well known, and Monte Carlo simulation packages that us…

Observation of $π^{-} K^{+}$ and $π^{+} K^{-}$ atoms

DIRAC Collaboration

The observation of hydrogen-like $π K$ atoms, consisting of $π^{-} K^{+}$ or $π^{+} K^{-}$ mesons, is presented. The atoms have been produced by 24 GeV/ $c$ protons from the CERN PS accelera…
