Hi everyone. I have a very quick question. Can someone tell me how to compute the energy dimensions of an n-point Green function. Consider for example a [itex]\lambda\phi^4[/itex] scalar theory. I know that the dimensions of an n-pt Green function are [itex]4-n[/itex] (or something like that). How do I prove it?(adsbygoogle = window.adsbygoogle || []).push({});

Thanks
