Soliton Decay in Coupled System of Scalar Fields

N. Riazi, A. Azizi, S. M. Zebarjad

A system of coupled scalar fields is introduced which possesses a spectrum of massive single-soliton solutions. Some of these solutions are unstable and decay into lower mass stabl…

Relativistic Kinetic Vertex in Positronium

S. M. Zebarjad, M. Haghighat

We derive Spinless Salpeter equation for the positronium using the NRQED Lagrangian. Consequently, we consider the Spinless Salpeter wavefunction instead of the Schrodinger wavefun…
