Abstract:

The SLD detector has a significant gap in its muon tracking coverage resulting from the redesign of the detector to meet earthquake safety standards. The 45-degree chambers are supplemental chamber planes added to recover tracking efficiency for muons in this gap between 0.65£|cosq|£0.85. This note describes the effort on the part of the University of Mississippi group to commission these chambers.

Abstract:

This note describes changes in the calculation of the inverse weight matrix, due to multiple scattering, for the 45-Degree Chamber implementation of the WIC track fitter.
