Title: Nucleon Energy Correlators as a Probe of Light-Quark Dipole Operators at the Electron-Ion Collider
Abstract: Light-quark electroweak dipole operators are important chirality-flipping BSM interactions, with direct connections to anomalous magnetic moments and electric dipole moments. However, collider probes of these operators usually suffer from quadratic suppression in unpolarized cross sections, making their effects difficult to explore.
In this talk, I will propose nucleon energy correlators (NEC) as a novel framework to probe electroweak light-quark dipole operators in deep inelastic scattering with an unpolarized nucleon. We construct a chiral-odd quark NEC that accesses quark transverse spin through azimuthal asymmetries in the energy flow of the target fragmentation region. These asymmetries provide clean and powerful observables, enabling linear constraints on the quark dipole couplings. This work establishes one of the first applications of energy correlator observables to new-physics searches and opens a promising direction for precision studies of chirality-flipping effects at the EIC.
Brief introduction about the speaker: Dr. Xuanbo Tong earned his Ph.D. from the Institute of Theoretical Physics, Chinese Academy of Sciences, in 2021. From 2021 to 2023, he served as a postdoctoral fellow at the Chinese University of Hong Kong, Shenzhen. Since 2023, he has been a postdoctoral researcher at the University of Helsinki and the University of Jyväskylä.
His research focuses on nucleon structure and spin effects, parton saturation, and phenomenology related to the electron-ion colliders. He is also interested in applying spin effects and QCD factorization to the search for new-physics signals.
