Optimized QCD two-loop correction to exclusive double production at B factories
Wen-Long Sang, Feng Feng, Yu Jia +3
We report the calculation of the process up to next-to-next-to-leading order (NNLO) at a center-of-mass (CM) energy of GeV. We employ an impro…

Strange-antistrange and charm-anticharm asymmetries of pion in 't Hooft model
Mingliang Zhu, Siwei Hu, Yu Jia +2
As a sequel of our preceding work [S. Hu et al., Phys. Rev. D 108 (2023) 9, 094040], we investigate the strange-antistrange and charm-anticharm asymmetries in the parton distributi…

Two-loop QCD corrections to Higgs radiative decay to vector quarkonium
Yu Jia, Zhewen Mo, Jia-Yue Zhang
The exclusive production of through Higgs boson radiative decay may serve a clean channel to extracting the charm quark Yukawa coupling. We calculate the two-loop QCD correct…
