Dynamics of the pionium with the density matrix formalism

The evolution of pionium, the pi /sup +/ pi /sup -/ hydrogen-like atom, passing through matter is described by the density matrix formalism in the first Born approximation. We compare the probability-based calculations with the more precise density matrix formalism which takes into account the inter...

description The evolution of pionium, the pi /sup +/ pi /sup -/ hydrogen-like atom, passing through matter is described by the density matrix formalism in the first Born approximation. We compare the probability-based calculations with the more precise density matrix formalism which takes into account the interference effects, and consider their influence on the pionium break-up probability. We apply our general result to the specific conditions of the DIRAC experiment at CERN.
