Abstract

The masses of excited charmed mesons are shown to decrease by (50150)\sim (50-150)~MeV due to a flattening of the confining potential at large distances, which effectively takes into account open decay channels. The scale of the mass shifts is similar to that in charmonium for ψ(4660)\psi(4660) and χc0(4700)\chi_{c0}(4700). The following masses of the first excitations: M(23P0)=2874M(2\,{}^3P_0)=2874~MeV, M(23P2)=2968M(2\,{}^3P_2)=2968~MeV, M(23D1)=3175M(2\,{}^3D_1)=3175~MeV, and M(23D3)=3187M(2\,{}^3D_3)=3187~MeV, and second excitations: M(31S0)=3008M(3\,{}^1S_0)=3008~MeV, M(33S1)=3062M(3\,{}^3S_1)=3062~MeV, M(33P0)=3229M(3\,{}^3P_0)=3229~MeV, and M(33P2)=3264M(3\,{}^3P_2) =3264~MeV, are predicted. The other states with L=0,1,2L=0,1,2 and nr3n_r \geq 3 have their masses in the region M(nL)3.3M(nL)\geq 3.3~GeV.
