Search for Long-Lived States of $\pi^+\pi^-$ Atoms: Addendum to the DIRAC Proposal

Mostrar otras versiones (1)

The proposed experiment is a further development of the DIRAC experiment already running at CERN PS. Up to now more than 21000 $\pi^+\pi^-$ pairs originated from the $\pi^+\pi^-$ atom ($A_{2\pi}$) breakup were identified and the overall accuracy of the $A_{2\pi}$ lifetime is about 9% in accordance w...
