Transverse Charge Distribution as a Probe of Nucleon Transversity
Wanchen Li, Xiaohui Liu, Ding Yu Shao
We introduce the transverse charge distribution as a spin-sensitive charge-flow probe for fragmentation and nucleon tomography. By measuring the angular distribution of net electri…
Azimuthal decorrelation in diffractive dijet production
Ding Yu Shao, Yu Shi, Cheng Zhang +2
We calculate the azimuthal angular decorrelation of diffractive dijets in ultra-peripheral heavy-ion, , and collisions to probe non-perturbative diffractive transverse mom…
Nested-GPT for variable-multiplicity parton showers: A case study in the resummation of non-global logarithms
Wanchen Li, Ding Yu Shao, Hao-Zhe Shi +1
We introduce Nested-GPT, a hierarchical autoregressive Transformer architecture for simulating the variable-multiplicity parton-shower histories. As a controlled benchmark, we stud…
Two-Dimensional Transverse-Momentum Subtraction and Semi-Inclusive Deep-Inelastic Scattering at NLO in QCD
Liang Dong, Shen Fang, Jun Gao +4
Identified hadron production is essential for the study of nucleon structure and QCD hadronization at high energies. We present the first calculation of unpolarized semi-inclusive…
Resummed azimuthal decorrelation and transverse momentum imbalance of dijets at the LHC
Rong-Jun Fu, Rudi Rahn, Ding Yu Shao +2
We present a theoretical study of the azimuthal decorrelation and transverse momentum imbalance in dijet production at the LHC, offering intriguing insights into the dyn…
Linearly Polarized Photon Fusion as a Precision Probe of the Tau Lepton Dipole Moments at Lepton Colliders
Ding Yu Shao, Hao Xiang, Fang Xu +2
We present a comprehensive investigation into the anomalous magnetic dipole moment () and electric dipole moment () of the lepton using the proc…
