Entanglement of back-to-back gluon pair
Lei Yang, Wen-Hao Yao, Yu-Kun Song +1
We investigate the polarization correlation of back-to-back gluon pairs in unpolarized collisions and compute their density matrix. For gluon pairs produced through …

Gluon Polarimetry with Energy-Energy Correlators
Yu-Kun Song, Shu-Yi Wei, Lei Yang +1
We propose a novel method to probe gluon linear polarization via energy correlations in hard scattering processes. This approach exploits the characteristic azimuthal mod…

Transverse spin correlation of back-to-back dihadron in unpolarized collisions
Lei Yang, Yu-Kun Song, Shu-Yi Wei
The spin correlation of back-to-back dihadron emerges in unpolarized high-energy collision, empowering unpolarized experiments to shed light on the spin-dependent fragmentation fun…
