Abstract:
We have studied pattern recognition in a variant of the proposed SD detector where the outer 5 layers (r=20-125 cm) have axial-only strips. The purpose of these studies is to determine if this detector, combined with a fully 3D (CCD) inner tracker, is sufficient for the reconstruction of tracks in the dense core of jets. Using standard algorithms, track finding efficiencies are presented for various track pT as a function of the distance from the jet center, and failure modes are discussed. The change in response due to detector inefficiencies and event backgrounds (pair BG, other beam BGs, and BGs from overlapping 2-photon reactions) are also investigated, as is the gain from crude tiling in the longitudinal direction.
