Accessing Nucleon Transversity with One-Point Energy Correlators
Abstract
We propose a novel probe of the nucleon's transversity distribution h_{1}^{q} using the one-point energy correlator (OPEC), an infrared-and-collinear safe jet substructure observable. We demonstrate that in transversely polarized p^{↑}p collisions, the OPEC exhibits a single-spin asymmetry (SSA) with a clean sin(ϕ_{s}-ϕ_{n}) angular dependence. This method probes SSA over a much wider kinematic range in the angular scale θ_{n} compared to traditional measurements of hadron transverse momentum j_{⊥}, establishing a complementary and systematically distinct channel to study the nucleon's three-dimensional structure at the RHIC and the future electron-ion collider.
