Description
We present the status of particle-flow algorithm development at Northern Illinois
University. A key element in our approach is the calorimeter-based "Directed Tree"
clustering algorithm. We have attempted to identify and tackle the essential
challenges and analyze the effect of several different approaches to the
reconstruction of jet energies and the Z-boson mass. A number of possibilities have
been studied, such as analog vs. digital energy measurement, hit density-based
clustering and the use of single or multiple energy thresholds (the so-called
"semi-digital" approach). We plan to use this PFA-based reconstruction to compare
some of the proposed detector technologies and geometries.
