A measure of clustering for a particle point-cloud. Transforms point-cloud into a graph, where node neighbourhood is determined by which particles fall within a distance on the \(\eta-\phi\) plane below radius. The clustering coefficients of these nodes are then computed.

Parameters:¶

pmu : MomentumArray¶

Four-momenta of particles in the point-cloud.

radius : float¶

Pairwise distance below which nodes are considered adjacent.

pseudo : bool¶

If True, will use pseudorapidity, rather than true rapidity. Default is True.

threads : int¶

Number of threads to use in the parallel portions of the calculation.

Returns:¶

Clustering coefficients of the particles in the point-cloud.

Return type:¶

ndarray[float32]
