"Continuation of Reconstruction Studies for the SiD Barrel Outer Tracker"

---

Current efforts involve implementing a Kalman filter fitting algorithm for the SiD simulation and reconstruction efforts in Java (JAS3, lcsim.org). This fitter will be made plug-compatible and available to SiD tracking developers, so it can be contrasted to the (existing) weight-matrix based fitter. In addition (or primarily), the addition or substitution of hits on a track in the Kalman framework will allow for the optimal resolution of hit sharing problems which occur near the center of jets.
