摘要：

The existence of a ground state of the Nelson Hamiltonian with perturbations of the form Sigma(4)(j=1) c(j)phi(j) with c(4) > 0 is considered. The self-adjointness of the Hamiltonian and the existence of a ground state are proven for arbitrary values of coupling constants. (C) 2011 American Institute of Physics. [doi:10.1063/1.3548076]
