Proposed Algorithms

HT+KF (Imperial College)

Hough Transform

provides seeds for the track fitting

Kalman filter fits

tracks through an iterative process Tracklet (USA)

Seeded by

projecting stubs from first two layers

Fitting by a 𝜓2

method Hybrid (Imperial & CERN)

Uses Tracklet

seeding process

Followed by a

Kalman Filter Combinatorial Kalman Filter (David Monk?)

Move the Kalman

Filter to as early a stage as possible in the process

Potential to greatly

improve performance
