Title: Thinking outside the ROCs: Designing decorrelated taggers (DDT) for jet substructure

Abstract

Here, we explore the scale-dependence and correlations of jet substructure observables to improve upon existing techniques in the identification of highly Lorentz-boosted objects. Modified observables are designed to remove correlations from existing theoretically well-understood observables, providing practical advantages for experimental measurements and searches for new phenomena. We study such observables in W jet tagging and provide recommendations for observables based on considerations beyond signal and background efficiencies.

Figure 1 Figure 1: Soft drop mass distribution (zcut = 0.1 and β = 0) for gluon jets after various cuts on $τ_{2}/τ_{1}$ (βτ = 1) for different jet pT bins: pT = 300–400 GeV (top left), pT = 500–600 GeV (top right), pT = 1–1.1 TeV (bottom left) and also formore » the signal (bottom right), distributions for signal are stable versus pT . The cuts in $τ_{2}/τ_{1}$ vary from 1.0 to 0.0 in steps of 0.02; the changing line styles for successive cuts are meant to visually aid the reader.« less
