Choose a decay tree

Create a fully configurable decay tree to analyze HEP events, designed for the processes you want to study. Include all the decay tree details or use a useful abstraction with only the features you are interested in.

Derive a basis

Each decay tree implicitly defines a complete basis of kinematic observables. Use masses, momenta, and decay angles, evaluated in any reference frame, to extract the most information from events.

Jigsaws under the hood

Whether your events contain combinatoric ambiguites due to identical final state particles or missing information resulting from one or more invisible particles, Recursive Jigsaw Reconstruction has you covered.

Analyze anything

Decay trees can be of arbitrary complexity with as many reconstructed or invisible particles as you like. The only limitation is the number of particles you reconstruct in your event and your imagination in choosing Jigsaws.
