I am asked to calculate renormalization for a massless $\phi^3$ theory in $d=6$ dimensional space using dimensional regularization. I'm having trouble finding the three-point vertex correction as one has to choose correct renormalization conditions. Does anyone know where I can read about this problem?

$\begingroup$ @ACuriousMind: Minor point concerning retagging: I would say that the specific-reference tag does not apply here cf. its tag wiki. $\endgroup$– Qmechanic ♦Jul 8, 2014 at 0:18

1$\begingroup$ @Qmechanic: I would say that the OP is essentially asking "What is the canonical source for X?" with X = DimReg of massless $\phi^3$ theory in six dimensions, but if you think that is interpreting the OP too much, I will not defend my tagging to death. (The QFT tag though...) $\endgroup$– ACuriousMind ♦Jul 8, 2014 at 0:21

1$\begingroup$ @ACuriousMind I agree with Qmechanic, the tag is very clearly not appropriate for this question, and accordingly I've removed it. A good guideline is that a question tagged with specific-reference should have exactly one correct answer, so unless there is and will only ever be one source that gives the three-point vertex correction for massless $\phi^3$ theory, this is not one of those questions. $\endgroup$– David ZJul 8, 2014 at 0:29

$\begingroup$ @ACuriousMind: In this case there could be a new canonical source tomorrow, and in such cases the specific-reference tag does not apply. $\endgroup$– Qmechanic ♦Jul 8, 2014 at 0:33
