Description
Precision physics at the HL-LHC will require novel techniques to distinguish hard QCD from pileup and beam jets (e.g. the identification of hadronic $W^+$ decay for electroweak measurements or boosted top tagging). One scheme is to identify the signature of QCD radiation inside of jets. The high particle-multiplicity of LHC multijets permits fine-grained investigation of the QCD radiation spectrum via $N$-point correlation functions. But even with a relatively simple example
-- the Fox-Wolfram moments at an $e^+ e^-$ collider -- high-frequency aliasing masks any useful information. We propose a general solution to suppress spectral leakage for any spatial correlation function.
