Polarized Semi-Inclusive Deep-Inelastic Scattering at in QCD
Liang Dong, Shen Fang, Jun Gao +4
Unraveling the partonic origin of the proton spin requires precise determinations of polarized parton distribution functions (PDFs), which depend on comparably precise theoretical…
NNLO QCD corrections to hadron production in DIS at finite transverse momentum
Liang Dong, Shen Fang, Jun Gao +3
We present the first calculation of hadron production in deep-inelastic scattering (DIS) at finite transverse momentum to next-to-next-to-leading order (NNLO) in perturbative QCD.…
Energy Correlators Resolving Proton Spin
Jun Gao, Hai Tao Li, Yu Jiao Zhu
We investigate the partonic origin of the proton longitudinal spin using spin-dependent energy correlators measured in lepton-hadron collisions with longitudinally polarized proton…
The NLO Twist-2 Matching of TMD Quark Transversity
Yu Jiao Zhu
We present the first next-to-next-to-next-to-leading order (NLO) calculation of the twist-2 matching coefficients for transverse momentum dependent (TMD) quark transversity par…
The NLO Twist-2 Matching of Helicity TMDs and SIDIS Spectrum
Yu Jiao Zhu
We compute the twist-2 matching of transverse momentum dependent (TMD) helicity parton distribution and fragmentation functions at next-to-next-to-next-to-leading order (NLO) i…
Two-loop QED corrections to the scattering of four massive leptons
Maximilian Delto, Claude Duhr, Lorenzo Tancredi +1
We study two-loop corrections to the scattering amplitude of four massive leptons in quantum electrodynamics. These amplitudes involve previously unknown elliptic Feynman integrals…
Topology and geometry of elliptic Feynman amplitudes
Claude Duhr, Yu Jiao Zhu
We report on the analytic computation of the 2-loop amplitude for Bhabha scattering in QED. We study the analytic structure of the amplitude, and reveal its underlying connections…
The Four Loop QCD Rapidity Anomalous Dimension
Ian Moult, Hua Xing Zhu, Yu Jiao Zhu
The rapidity anomalous dimension controls the scaling of transverse momentum dependent observables in the Sudakov region. In a conformal theory it is equivalent to the soft anomalo…
Double soft current at one-loop in QCD
Yu Jiao Zhu
We investigate the soft behavior of QCD amplitudes involving multiple Wilson lines and derive compact analytic expressions for double soft gluon and double soft quark emissions at…
