Description

Current status: developing a new metric for scoring vertex candidates, with a metric that tries to assess whether a given candidate would require an implausible 'energy kick' in order to yield the resulting Hit topologies. It's not clear yet how this will interact with the existing Hit r-phi score, but it does seem to introduce some new information.

History

#1 Updated by John Marshall almost 3 years ago

  • % Done changed from 0 to 90

Obtain score to select neutrino interaction Vertex from list of candidate positions. New algorithm uses 2D Clusters and calorimetric info to decide: EnergyKickVertexSelection.
Previously, used distribution of Hits around each candidate to obtain score, then ‘beam deweighting’ to favour upstream candidates. This alg still available: HitAngleVertexSelection.

New score has three components:
-Energy kick score: assess suitability of candidate by examining transverse components of Cluster energies with respect to candidate position.
-Energy asymmetry score: candidates that bisect a Cluster, or two well-aligned Clusters, can be suppressed.
-Beam deweighting score: unchanged.

Associated pattern recognition performance shown at MicroBooNE collaboration meeting.
