Utilizing comprehensive experimental data on charmed mesons, we systematically investigate masses of the higher radial and orbital excitations of the D and Ds meson families using the relativistic flux tube model. Our study employs mass splitting induced by spin-dependent interactions within the j-j coupling scheme. Our predicted masses align well with the experimental measurements for the well-established D and Ds states. However, anomalous resonances such as Ds0(2317) and Ds1(2460) do not align with conventional meson states within our theoretical framework. Based on our reliable mass predictions for low-lying states, we propose spectroscopic assignments for several recently observed high-mass resonances: D2(2740)0, D^*3(2750), D0(2550)0, D^*1(2600)0, D1^*(2760)0, D^*J(3000), DJ(3000), D^*2(3000), D^*s1(2860)± and D^*s3(2860)±.Additionally, the resonance DsJ(3040)+ is identified as a 2P excitation with spin-parity quantum numbers JP = 1+. Extending our model, we also calculate the mass spectra of doubly charmed Ξcc and Ωcc baryons within the heavy-diquark-light-quark picture. These theoretical predictions provide crucial guidance for ongoing and future experimental searches for higher radial and orbital excitations in the charmed meson and doubly charmed baryon sectors.
