Chiral radiative corrections in potential model and the P-wave states of heavy-light mesons

In relativistic potential model of heavy-light mesons it is essential to incorporate the chiral radiative corrections before comparing the model predictions with data. Once the radiative corrections are taken into account the potential model can explain the unusual mass spectra and absence of the spin orbit-inversion in P-wave states.Comment: Talk presented at The 4th International Conference on Flavor Physics, Sep. 24-28, 2007, Beijin
