西南理论物理中心系列报告:Energy Energy correlators in DIS

报告摘要：The Energy-Energy Correlator is an observable that explores the angular correlations of energy depositions in detectors at high-energy collider facilities. It has been extensively studied in the context of precision QCD. In this presentation, I will discuss our recent work on the energy-energy correlator in the context of Deep Inelastic Scattering. In the limit where the energy emissions are back-to-back, the proposed observable is sensitive to the universal transverse momentum-dependent parton distribution functions and fragmentation functions. In the collinear limit, a definition of the nuclear energy-energy correlator was introduced. We would revisit the NEEC definition, which involves weighting the EEC by Bjorken x, and conducting the study across the entire phase space region.
