Abstract We study the heavy-light mesons within basis light-front quantization. The resulting mass spectra of D , $$$$D_s$$$$ $D_{s}$ , B , and $$$$B_s$$$$ $B_{s}$ agree reasonably well with experiments. We also predict states which could be measured in the near future. In the light-front formalism, we calculate the light-front wave functions and additional experimental observables, such as parton distribution functions, distribution amplitudes, and decay constants by means of integrations over light-front wave functions. We also provide ratios of decay constants for selected pseudoscalar meson decays ( $$$$D_s$$$$ $D_{s}$ to D and $$$$B_s$$$$ $B_{s}$ to B ) as they may prove to be theoretically more robust and more reliably determined in experiments. We find that our ratios are systematically smaller than existing experiments and other approaches by 5–18%.
