Eleventh-order calculation of Ising-limit Green’s functions for scalar quantum field theory in arbitrary space-time dimension<i>D</i>
This paper extends an earlier high-temperature lattice calculation of the renormalized Green's functions of a $D$-dimensional Euclidean scalar quantum field theory in the Ising limit. The previous calculation included all graphs through sixth order. Here, we present the results of an eleventh-order calculation. The extrapolation to the continuum limit in …
