Unquenched quark model calculations show coupled-channel effects lower masses of higher D and Ds excitations; D_s1(2933) is assigned as mixed D_s(2P1), D_sJ(3040) favors D_s(3^1S0), while D(3000) fits none of the 3S/2P/2D/1F states.
The broad stateD sJ(3040)+ can be well explained with the Ds(31S 0) assignment when coupled-channel effects are con- sidered

Higher excited charmed and charmed-strange mesons in an unquenched quark model
Unquenched quark model calculations show coupled-channel effects lower masses of higher D and Ds excitations; D_s1(2933) is assigned as mixed D_s(2P1), D_sJ(3040) favors D_s(3^1S0), while D(3000) fits none of the 3S/2P/2D/1F states.
