Relationship of pionium lifetime with pion scattering lengths in generalized chiral perturbation theory
H. Sazdjian
The pionium lifetime is calculated in the framework of the quasipotential-constraint theory approach, including the sizable electromagnetic corrections. The framework of generalize…

The pionium lifetime in generalized chiral perturbation theory
H. Sazdjian
Pionium lifetime corrections to the nonrelativistic formula are calculated in the framework of the quasipotential-constraint theory approach. The calculation extends an earlier eva…
