madgraph.core.drawing.VertexPoint:
Extension of the class Vertex in order to store the information
linked to the display of a FeynmanDiagram, as position
madgraph.core.color_amp.ColorMatrix:
A color matrix, meaning a dictionary with pairs (i,j) as keys where
i and j refer to elements of color basis objects.
madgraph.core.diagram_generation.Amplitude:
Amplitude: process + list of diagrams (ordered) Initialize with a
process, then call generate_diagrams() to generate the diagrams for
the amplitude
madgraph.core.helas_objects.HelasAmplitude:
HelasAmplitude object, has the information necessary for writing a
call to a HELAS amplitude routine:a list of mother wavefunctions,
interaction id, amplitude number
madgraph.core.helas_objects.HelasDecayChainProcess:
HelasDecayChainProcess: If initiated with a DecayChainAmplitude
object, generates the HelasMatrixElements for the core process(es)
and decay chains.
madgraph.core.helas_objects.HelasDiagram:
HelasDiagram: list of HelasWavefunctions and a HelasAmplitude, plus
the fermion factor associated with the corresponding diagram.
madgraph.core.helas_objects.HelasMultiProcess:
HelasMultiProcess: If initiated with an AmplitudeList, generates
the HelasMatrixElements for the Amplitudes, identifying processes
with identical matrix elements
madgraph.core.helas_objects.HelasWavefunction:
HelasWavefunction object, has the information necessary for writing
a call to a HELAS wavefunction routine: the PDG number, all
relevant particle information, a list of mother wavefunctions,
interaction id, all relevant interaction information, fermion flow
state, wavefunction number
madgraph.core.base_objects.Interaction:
The interaction object containing the whole set of information
required to univocally characterize a given type of physical interaction:
madgraph.core.base_objects.Particle:
The particle object containing the whole set of information
required to univocally characterize a given type of physical
particle: name, spin, color, mass, width, charge,...
madgraph.various.misc.BackRead:
read a file returning the lines in reverse order for each call of
readline() This actually just reads blocks (4096 bytes by default)
of data from the end of the file and returns last line in an
internal buffer.
madgraph.core.color_algebra.ColorString:
A list of ColorObjects with an implicit multiplication between,
together with a Fraction coefficient and a tag to indicate if the
coefficient is real or imaginary.
