A study of topological vertexing for heavy quark tagging

TL;DR

This paper evaluates how different inner radii in vertex detectors affect heavy quark tagging efficiency, demonstrating that smaller radii improve charm tagging performance using topological vertexing techniques.

Contribution

It provides a comparative analysis of vertex detector radii on heavy quark tagging efficiency, highlighting benefits for charm tagging with smaller inner radii.

Findings

Charm tagging efficiency increases with smaller inner radii.

Topological vertexing technique effectively distinguishes heavy quarks.

Detector design impacts heavy quark tagging performance.

Abstract

We compare heavy quark tagging and anti-tagging efficiencies for vertex detectors with different inner raddi using the topological vertex technique developed at the SLC/SLD experiment. Charm tagging benefits by going to very small inner radii.
