| Nov 3, 2016 at 17:30 | comment | added | quarkonium | I want to find only the connected diagrams for phi 4 theory using tha above formalism. But it seems we need to find functional derivative of logarithm of a differential (inside integral) which acts on an integral containing J's (sources).But isn't this formalism supposed to be more useful compared to other technique where disconnected diagrams also appear. Please suggest or refer to some article so that I can use this to find connected diagrams efficiently. Also I ask is it even possible? Thank you. | |
