                                     LoopHelasDiagram

LoopHelasDiagram object, behaving exactly as a Diagram except that it has a couple of additional functions which can reconstruct and handle loop amplitudes.

Method Details [hide private]

get_regular_amplitudes(self)

source code 

Quick access to ALL non-loop amplitudes, including those which are inside the LoopAmplitudes defined in this diagram.

Overrides: core.helas_objects.HelasDiagram.get_regular_amplitudes

get_ct_amplitudes(self)

source code 

Quick access to the regular amplitudes defined directly in this diagram (not in the LoopAmplitudes). Usually they correspond to the counter-terms.
