Predstavljen je pojav oscilacij (mešanja) nevtralnih mezonov. Pojav je opisan prek Feynmanovih diagramov in kvantitativno z reševanjem Schrodingerjeve enačbe z efektivnim Hamiltonovim operatorjem. Podrobneje sta opisana pojav mešanja mezonov D0 in postopek določanja mešalnega parametra y. Sledijo še rezultati meritev z detektorjem Belle omenjenega mešalnega parametra za mešanje sistema mezonov D0.
A phenomenon of oscillations (mixing) of neutral mesons is presented. The phenomenon is described through Feynman’s diagrams and quantitatively by solving Schrodinger’s equation with effective Hamiltonian Operator. A phenomenon of mixing mesons D0 is described in more detail as well as a process of determining a mixing parameter y. This is followed by results of measurements of Belle detector, the mentioned mixing parameter for mixing a system of mesons D0.
