Projected Energy Correlators: Two-Loop Jet Functions and NNLL Resummation
Kyle Lee, Yibei Li, Zhen Xu +1
We present the next-to-next-to-leading logarithmic (NNLL) collinear resummation of projected -point energy correlators (ENCs) up to , matched to fixed-order predictions at…

On the Edge of Safety: Charge-Charge Correlation in the Back-to-Back Limit
Pier Francesco Monni, Gherardo Vita, Zhen Xu +1
We investigate the Charge-Charge Correlation (QQC) in electron-positron annihilation as a probe of charge dynamics in Quantum Chromodynamics. While generally divergent beyond leadi…

Scaling violation in power corrections to energy correlators from the light-ray OPE
Hao Chen, Pier Francesco Monni, Zhen Xu +1
In recent years, energy correlators have emerged as a powerful tool to explore the field theoretic structure of strong interactions at particle colliders. In this Letter we initiat…
