Probing Gluon Linear Polarization with Dihadron Fragmentation in Decays
Zhi-Guo He, Guanghui Li, Yang Liu +3
The dihadron fragmentation function (DiFF) of a linearly polarized gluon has not yet been accessed experimentally, leaving an important aspect of spin-dependent gluon hadronization…
Quantum Information of Photon Pairs at Lepton Colliders
Kun Cheng, Tao Han, Guanghui Li +1
Photon pairs have provided an ideal laboratory for exploring entanglement and Bell inequality violation in low-energy experiments. Extending such studies to high-energy colliders i…
Probing the Color-Octet Mechanism via Dihadron Fragmentation in Decays
Zhi-Guo He, Guanghui Li, Yu-Jie Tian +2
The color-octet (CO) mechanism is a cornerstone of non-relativistic QCD, yet its long-distance matrix elements remain limited, preventing stringent tests of the theory. We demonstr…
Probing Quark Electromagnetic Properties via Entangled Quark Pairs in Fragmentation Hadrons at Lepton Colliders
Qing-Hong Cao, Guanghui Li, Xin-Kai Wen +1
Electromagnetic dipole interactions of light quarks induce distinct spin correlations in quark pairs produced at lepton colliders, favoring entangled spin-triplet state aligned alo…
Lam-Tung relation breaking effects and weak dipole moments at lepton colliders
Guanghui Li, Xu Li, Bin Yan
The breaking of the Lam-Tung relation in the Drell-Yan process at the LHC exhibits a long-standing tension with the Standard Model (SM) prediction at accuracy…
