Photoproduction of K* meson off the proton target with the Regge contributions
We investigate the K* Λ(1116) photoproduction off the proton target by employing the treelevel Born approximation within the effective Lagrangian...

Scalar mesons in η′ → ηπ 0 π 0 decay
The decay η ′ → ηπ 0 π 0 is studied in the framework of isobar model. It is shown, that good agreement with the experiment is achieved if α ...

Quantum Gravity, CPT symmetry and entangled states
There may be unique (“smoking-gun”) signatures of the breakdown of CPT symmetry, induced in some models of Quantum Gravity entailing decoherence for...

RQM description of the charge form factor of the pion and its asymptotic behavior
The pion charge and scalar form factors, F 1 ( Q 2 ) and F 0 ( Q 2 ) , are first calculated in different forms of relativistic quantum mechanics. This is...

Anticrossing in the η-η′ complex
The Dyson-Schwinger approach to mesons as quark-antiquark bound states produces a very satisfactory description of the whole light pseudoscalar...

CP measurement in quantum teleportation of neutral mesons
Quantum teleportation using neutral pseudoscalar mesons shows novel connections between particle physics and quantum information. The projection...
