Measurement of jet track functions in pp collisions at √s = 13 TeV with the ATLAS detector
Published in Physics Letters B, 2025
This analysis presents the first measurement of jet track functions, which characterize the distribution of charged-particle momentum fractions inside jets, using the full ATLAS Run 2 dataset at √s = 13 TeV. The OmniFold algorithm enables an unbinned, high-dimensional unfolding that gives direct access to moments of the track function and the first measurement of their renormalization group flow.
