Phys. Rev. D 64, 114023 (2001) [13 pages]Application of Pauli-Villars regularization and discretized light-cone quantization to a single-fermion truncation of Yukawa theoryReceived 5 July 2001; published 12 November 2001 We apply Pauli-Villars regularization and discretized light-cone quantization to the nonperturbative solution of (3+1)-dimensional Yukawa theory in a single-fermion truncation. Three heavy scalars, including two with negative norm, are used to regulate the theory. The matrix eigenvalue problem is solved for the lowest-mass state with use of a new, indefinite-metric Lanczos algorithm. Various observables are extracted from the wave functions, including average multiplicities and average momenta of constituents, structure functions, and a form factor slope. © 2001 The American Physical Society URL:
