Web7 de sept. de 2024 · In this formalism, the mixing rate is governed by two parameters. The first, x, is proportional to the mass difference between the two eigenstates while the second, y, is proportional to the lifetime difference. Meson mixing occurs through intermediate states reached through the decays of P 0 and P 0. For example, both D 0 and D 0 can decay to ...

Webwhich arises naturally when the squared mass of each meson depends linearly on the squared mass of the pion. This relation is analogous to the Rydberg formula for the hydrogen spectrum, with the electron mass replaced by the pion mass.
