Creates a ParticleSet instance directly from numpy arrays.

Parameters:¶

pdg : ndarray[int32], optional¶

PDG codes.

pmu : ndarray[float64] or ndarray[void], optional¶

Four momenta, \(p_\mu\), formatted as a structured array with fields ('x', 'y', 'z', 'e') or an unstructured array with columns in that order.

color : ndarray[int32] or ndarray[void], optional¶

Color / anti-color pairs, formatted in columns of ('color', 'anticolor'), or as a structured array with those fields.

helicity : ndarray[int16], optional¶

Helicity values.

status : ndarray[int32], optional¶

Status codes from Monte-Carlo event generator.

final: ndarray[Any, dtype[bool_]] | None = None¶

Boolean array indicating which particles are final state.

Returns:¶

A composite object, wrapping the data provided in Graphicle objects, and providing a unified interface to them.

Return type:¶

ParticleSet
