Research output: Contribution to journalArticlepeer-review


We use the light-front coupled-cluster (LFCC) method to compute the odd-parity massive eigenstate of ϕ1+14 theory. A standard Fock-space truncation of the eigenstate yields a finite set of linear equations for a finite number of wave functions. The LFCC method replaces Fock-space truncation with a more sophisticated truncation; the eigenvalue problem is reduced to a finite set of nonlinear equations without any restriction on Fock space, but with restrictions on the Fock wave functions. We compare our results with those obtained with a Fock-space truncation.
