Keywords track reconstruction, vertex finding, fitting
Student levels Advanced undergrads
Learning objectives Introduce the concept of track fitting using the example of a straight line fit,
Understand the meaning of track impact parameter and calculate the dependence of impact parameter resolution on the relevant detector parameters,
Use Monte Carlo techniques to demonstrate that the decay products of long-lived particles can be "tagged" by selecting tracks with high impact parameter,
Use the example of a simple two-body decay to introduce the topic of secondary vertex reconstruction
