The precise graph convention

The one-loop coefficient and its graph inventory › The precise graph convention · lines 1371–1387

At order $κ$ , the relevant leg types are

vertex V_{1, g} [h, ϕ] V_{1, g} [h_{cl}, ϕ] mixed metric quadratic vertex S_{3} [h] background ghost quadratic vertex ghost-metric vertex quantum legs h ϕϕ ϕϕ hh hhh c ˉ c h c ˉ c

Only $h ϕϕ$ carries both a metric and a scalar leg without a background coefficient.
