Bonus: Calibrating a jet subtructure tagger.

Overview

Teaching: 15 min
Exercises: 45 min

Questions

• How can I validate a jet substructure tagger in data?

• What can be done if a tagger (object-selection technique) performs differently in data vs simulation?

Objectives

• Implement a selection that is enriched in boosted W bosons and top quarks.

• Extract efficiency scale factors.

Key Points

• We can define tagger scale factors by measuring the efficiency of the tagger in t+W enriched regions.
