One possibility is to have 6 iterations: 3 using OI state based seeding, followed by 3 IO hit based seeding. These 3 iterations for each seeding mechanism will first target high pT prompt muons, then low pT prompt muons and finally displaced muons. With this format of iterations, additional iterations can be included in the future, and iterations deemed to have poor performance can be removed.

The seeding for the IO-hit based algorithm could be based off of the same method as the current online iterative tracking; which takes pixel tracks.

 

 

Comments from Current Design

The trajectory seed builder for OIState uses: TSGForRoadSearch: class generates hit-less TrajectorySeed from a given Track (=L2 cand). the original error matrix of the Track is adjusted (configurable). In particular for OIState: TSGForRoadSearch::makeSeeds_3.
