Emergence of kaonium as a sharp resonance in photon-photon to meson-meson cross-sections

Alireza Beygi, S. P. Klevansky, R. H. Lemmer

We calculate the binding energies of the hypothetical mesonic atom, $K^{+} K^{-}$ (kaonium), using the $K^{+} K^{-} \to K^{+} K^{-}$ elastic scattering amplitude. Our findings are in line with…

Three perspectives on entropy dynamics in a non-Hermitian two-state system

Alexander Felski, Alireza Beygi, Christos Karapoulitidis +1

A comparative study of entropy dynamics as an indicator of physical behavior in an open two-state system with balanced gain and loss is presented. We distinguish the perspective ta…
