Abstract

© 2021, Pleiades Publishing, Ltd.Abstract: The masses of excited charmed mesons are shown to decrease by $${\sim}$$(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 $$\psi$$(4660) and $$\chi_{c0}$$(4700). The following masses of the first excitations: $$M(2^{3}P_{0})=2874$$ MeV, $$M(2^{3}P_{2})=2968$$ MeV, $$M(2^{3}D_{1})=3175$$ MeV, and $$M(2^{3}D_{3})=3187$$ MeV, and second excitations: $$M(3^{1}S_{0})=3008$$ MeV, $$M(3^{3}S_{1})=3062$$ MeV, $$M(3^{3}P_{0})=3229$$ MeV, and $$M(3^{3}P_{2})=3264$$ MeV, are predicted. The other states with $$L=0$$, 1, 2 and $$n_{r}\geqslant 3$$ have their masses in the region $$M(nL)\geqslant 3.3$$ GeV.
