Pionium in the elementary particle decays

High Energy Physics - Phenomenology 2011-07-19 v2

Abstract

Some atomic decays of elementary particles with pionium (π+π\pi^+\pi^--dimesoatom) in the final state are considered. Only for K-meson atomic decays are the corresponding branching ratios big enough to make their experimental study realistic. The O(α)O(\alpha) order corrections to the lifetime of pionium are also calculated.
