Reconstruction

Field Issues

This is meant to be a central location for finding reconstruction-related items which have some field dependences.

AuAu200 (2005)
proton-Lambda HBT
h+/h- ratio (odd pt shape, but same between fields)
Track and V0 reconstruction (general agreement between fields?)
AuAu200 (2003)
Xi decay analyses - use of a greater decay length cut seemed to alleviate the differences seen in Xi+/Xi- ratio

Current Work on Tracking/Fitting Tools

The group is currently looking into some of the options for improving the global tracking and fitting. These options include an implementation of GEANE as a universal track propagation engine, providing an interface between tracking and geometry/material info, and using Kalman filtering techniques to obtain the best estimation of track parameters.
