1 / m corrections for orbitally excited heavy mesons and the 1 / 2 – 3 / 2 puzzle

1 / m corrections for orbitally excited heavy mesons and the 1 / 2 – 3 / 2 puzzle

We reinvestigate the effects of the 1/m sub(c) corrections on the spectrum of the lowest orbitally excited D-meson states. We argue that one should expect the 1/m sub(c) corrections to induce a significant mixing between the two lowest lying 1 super(+) states. We discuss the implications of this mix...

Zusammenfassung:We reinvestigate the effects of the 1/m sub(c) corrections on the spectrum of the lowest orbitally excited D-meson states. We argue that one should expect the 1/m sub(c) corrections to induce a significant mixing between the two lowest lying 1 super(+) states. We discuss the implications of this mixing and compute its effect on the semileptonic decays B arrow right D**l[nu] and the strong D** decays.
