On chiral excitations with exotic quantum numbers
We consider the flavour sextet of charmed meson resonances with JP=1+ quantum numbers that is predicted by the leading order chiral Lagrangian with up, down and strange quarks. The effect of chiral correction terms as determined previously from QCD lattice data is worked out. Pole masses in the comp...
