Investigation of Efficient Analysis Techniques for Z→ττ with Shrinking Cone Method

This document outlines a series of action items aimed at enhancing the efficiency of the analysis of Z→ττ decays. It proposes the use of the shrinking cone move analysis to optimize cut parameters and improve event selection. Key points include investigating relative isolation criteria, adjusting HCAL isolation cuts, and building a validation package for the tau group. The goal is to better estimate the cross-section error and ensure the analysis is as effective as anticipated. Collaboration with Mike B. is essential for review and consultation on method improvements.

  2. Action Items • Pursue using a shrinking cone move analysis to 31X. • Requested W->eυ which will give me all needed samples. • Is shrinking cone tau and standard id cuts as efficient as we expect investigate and consult with Mike B. • Something is messed up. • Investigate relative isolation with a floor(1 GeV floor?) and a looser HCAL isolation cut. Re-optimize these cuts in three series with higher statistics. • Move toward completing physics analysis, Estimate Z->tautau cross section error. • Build Z->etau validation package for the tau group • Looked at this briefly Joshua Swanson
