Heavy-light mesons on the light front
Abstract We study the heavy-light mesons within basis light-front quantization. The resulting mass spectra of D, $$D_s$$ Ds , B, and $$B_s$$ Bs 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 li...

| description | Abstract We study the heavy-light mesons within basis light-front quantization. The resulting mass spectra of D, $$D_s$$ Ds , B, and $$B_s$$ Bs 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 ($$D_s$$ Ds to D and $$B_s$$ Bs 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%. |
