Heavy-Light Mesons on the Light Front

Understand

We study the heavy-light mesons within basis light-front quantization.

• The resulting mass spectra of $D$, $D_s$, $B$, and $B_s$ 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.
