Neutral pion decay in dense skyrmion matter
Alexander C. Kalloniatis, Byung-Yoon Park
We study the density dependence of the decay using the Skyrme Lagrangian to describe simultaneously both the matter background and mesonic fluctuations. Pion properties…

Spectral density in resonance region and analytic confinement
Alex C. Kalloniatis, Sergei N. Nedelko, Lorenz von Smekal
We study the role of finite widths of resonances in a nonlocal version of the Wick-Cutkosky model. The spectrum of bound states is known analytically in this model and forms linear…
