Strong and radiative D decays

We use the relativistic light-front quark model to show that both strong and radiative D * decays are in good agreement with the 1992 CLEO II results. In particular the coupling for D * → Dπ is consistent with the experimental upper limit. The key point is the relativistic treatment of the quark spi...

Description
Summary:We use the relativistic light-front quark model to show that both strong and radiative D * decays are in good agreement with the 1992 CLEO II results. In particular the coupling for D * → Dπ is consistent with the experimental upper limit. The key point is the relativistic treatment of the quark spin.
