Abstract

We apply the recently developed concept of the nucleon energy-energy correlator (NEEC) for the gluon sector to investigate the long-range azimuthal angular correlations in proton-proton collisions at the Large Hadron Collider. The spinning gluon in these collisions will introduce substantial nonzero $cos (2 ϕ)$ asymmetries in both Higgs boson and top quark pair productions, where $ϕ$ is the azimuthal angle between the forward and backward energy correlators in the NEEC observables. The genesis of the $cos (2 ϕ)$ correlation lies in the intricate quantum entanglement. Owing to the substantial $cos (2 ϕ)$ effect, the NEEC observable in Higgs boson and $t \bar{t}$ production emerges as a pivotal avenue for delving into quantum entanglement and scrutinizing the Bell inequality at high-energy colliders.
