Light-front holography and the light-front coupled-cluster method

We explore a combination of light-front holographic QCD and the nonperturbative light-front coupled-cluster (LFCC) method in the context of a quark model for mesons. The LFCC method converts the meson eigenstate problem of QCD into an effective eigenproblem in the valence quark-antiquark Fock sector. Light-front holography then provides an analytically solvable model for the valence sector, which can be used as a starting point for the solution of the LFCC eigenproblem. Within this context, we extend the holographic eigenproblem for mesons to include massive quarks and a calculable longitudinal wave function. Results are compared with those obtained with the Brodsky-deTeramond ansatz.
