摘要：

The mass difference of c and u quarks is similar to the energy needed to excite gluonic degrees of freedom in strong QCD. This underpins the degeneracy of D and a recently observed candidate hybrid excitation of the pi at similar to 1.8 GeV and may generate a strong analogue of Penguin mixing together with a measurable CP-violation in D and D-s decays.
