dc.titleDetection of pi(+)pi(-) atoms with the DIRAC spectrometer at CERNen
heal.abstractThe goal of the DIRAC experiment at CERN is to measure with high precision the lifetime of the pi(+)pi(-) atom (A(2pi)), which is of order 3 x 10(-15) s, and thus to determine the s-wave pipi-scattering lengths difference \a(0) - a(2)\. A(2pi) atoms are detected through the characteristic features of pi(+)pi(-) 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.en
