Next-to-next-to-leading-order QCD corrections to gluon fragmentation function for quarkonium

Feng Feng, Yu Jia, Wen-Long Sang

We present the first computation of the next-to-next-to-leading-order (NNLO) QCD corrections to the gluon fragmentation function for quarkonium within the nonrelati…

Deeply virtual pion production through two-loop order

Wen Chen, Feng Feng, Yu Jia +3

Deeply virtual meson production (DVMP) is among the most prominent channels to extract the nucleon's generalized parton distributions (GPDs) at scattering facilities such as {…

Exclusive Decays of the Fully Heavy Tetraquarks into Light Mesons

Feng Feng, Ming-Ming Liu

In this work, we investigate the exclusive decays of the fully heavy tetraquark states into light mesons, specifically and , using the framework of Non-Relativis…

Mixed Electroweak-QCD Corrections to

Wen-Long Sang, Feng Feng, Yu Jia

We present for the first time the complete three-loop mixed electroweak-QCD () corrections for the decay channel , by implementing three different…

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 imp…

Next-to-leading-order QCD corrections to nucleon Dirac form factors

Long-Bin Chen, Wen Chen, Feng Feng +2

The leading-order perturbative QCD (pQCD) predictions to nucleon electromagnetic form factors were first made in late 70s. In this Letter for the first time we accomplish the calcu…
