Investigation of $K^{+} K^{-}$ pairs in the effective mass region near $2 m_{K}$

B. Adeva, L. Afanasyev, A. Anania +53

The DIRAC experiment at CERN investigated in the reaction $p (24 GeV /c) + Ni$ the particle pairs $K^{+} K^{-}, π^{+} π^{-}$ and $p p ˉ$ with relative momentum $Q$ in the pair s…

First measurement of a long-lived $π^{+} π^{-}$ atom lifetime

B. Adeva, L. Afanasyev, A. Anania +56

The adapted DIRAC experiment at the CERN PS accelerator observed for the first time long-lived hydrogen-like $π^{+} π^{-}$ atoms, produced by protons hitting a beryllium target. A part…

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…

Evidence for $π K$ -atoms with DIRAC

B. Adeva, L. Afanasyev, Y. Allkofer +77

We present evidence for the first observation of electromagnetically bound $π^{\pm} K^{\mp}$ -pairs ( $π K$ -atoms) with the DIRAC experiment at the CERN-PS. The $π K$ -atoms are produced by…

First measurement of the $π^{+} π^{-}$ atom lifetime

The DIRAC collaboration

The goal of the DIRAC experiment at CERN (PS212) is to measure the $π^{+} π^{-}$ atom lifetime with 10% precision. Such a measurement would yield a precision of 5% on the value of the $…

Spin Structure of the Proton from Polarized Inclusive Deep-Inelastic Muon-Proton Scattering

D. Adams

We have measured the spin-dependent structure function $g_{1}^{p}$ in inclusive deep-inelastic scattering of polarized muons off polarized protons, in the kinematic range $0.003 < x <…

Spin Asymmetry in Muon--Proton Deep Inelastic Scattering on a Transversely-Polarized Target

The Spin Muon Collaboration

We measured the spin asymmetry in the scattering of 100 GeV longitudinally-polarized muons on transversely polarized protons. The asymmetry was found to be compatible with zero in…
