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…

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…
