Physical Review Letters, 133(7), 071903. https://doi.org/10.1103/PhysRevLett.133.071903https://hdl.handle.net/1911/117860Energy correlators that describe energy-weighted distances between two or three particles in a hadronic jet are measured using an event sample of √𝑠=13 TeV proton-proton collisions collected by the CMS experiment and corresponding to an integrated luminosity of 36.3 fb−1. The measured distributions are consistent with the trends in the simulation that reveal two key features of the strong interaction: confinement and asymptotic freedom. By comparing the ratio of the measured three- and two-particle energy correlator distributions with theoretical calculations that resum collinear emissions at approximate next-to-next-to-leading-logarithmic accuracy matched to a next-to-leading-order calculation, the strong coupling is determined at the 𝑍 boson mass: 𝛼𝑆⁡(𝑚𝑍)=0.122⁢9+0.0040−0.0050, the most precise 𝛼𝑆⁡(𝑚𝑍) value obtained using jet substructure observables.engExcept where otherwise noted, this work is licensed under a Creative Commons Attribution (CC BY) license.  Permission to reuse, publish, or reproduce the work beyond the terms of the license or beyond the bounds of fair use or other exemptions to copyright law must be obtained from the copyright holder.Journal articlePhysRevLett-133-071903https://doi.org/10.1103/PhysRevLett.133.071903
