Possibly very silly question in QFT. Consider the Lagrangian for a scalar field theory.(adsbygoogle = window.adsbygoogle || []).push({});

A term like

g/φ^2

should be renormalizable on power counting arguments. The mass dimension of g should be

2 (D-1)

where D is the number of space-time dimensions.Does this make sense?
