Energy correlators can convert scaling violations into angular bump hunting for new physics, yielding projected competitive LHC sensitivity for a light hadrophilic Z'.
A new approach using near-side energy-energy correlators in dihadron fragmentation enables extraction of nucleon transversity PDF in collinear factorization without modeling intrinsic transverse momentum or dihadron resonances.
The paper proposes that one-point energy correlators in transversely polarized proton-proton collisions access the nucleon's transversity distribution through a single-spin asymmetry with sin(φ_s - φ_n) angular dependence over a wider kinematic range than traditional transverse momentum measurements
A multi-stage CoLBT-hydro simulation with a 2 GeV medium scale reproduces the CMS in-jet EEC and predicts rank- and rapidity-gap-dependent modifications that encode path length and the diffusion wake.
Numerical predictions for transverse-spin dependent energy-energy correlators in polarized pp collisions agree with recent STAR data and show a slight preference for transversity extractions consistent with lattice QCD.
