Description
  • The goal of the DIRAC experiment at CERN is to measure with high precision the lifetime of the π+π- atom (A2π), which is of order 3 x 10-15 s, and thus to determine the s-wave ππ-scattering lengths difference |a0 - a2|. A2π atoms are detected through the characteristic features of π+π- pairs from the atom break-up (ionization) in the target. We report on a first high statistics atomic data sample obtained from p-Ni interactions at 24 GeV/c proton momentum and present the methods to separate the signal from the background.

  • Cílem experimentu DIRAC v CERNU je změření střední doby života π+π- atomů (A2π). Tato doba je řádově 3 x 10-15 s. Dalším cílem tohoto experimentu je určení s-vlnových délek ππ rozptylu. V článku jsou uvedena data získaná interakcí 24 GeV protonu s Ni terčem, způsob získání signálu z π+π- atomů vyletujících z terče a odlišení tohoto signálu od pozadí. (cs)
