Confronting perturbative QCD with the hardest exclusive reactions: kaon electromagnetic form factors
Long-Bin Chen, Wen Chen, Feng Feng +1
Among countless channels of hard exclusive reactions, the kaon electromagnetic form factors (EMFFs) are of special interest, which have been measured up to $Q^2 \sim 50\;{\rm GeV}^…
Light quark mass dependence of nucleon mass to two-loop order
Long-Bin Chen, Siwei Hu, Yu Jia +1
We investigate the nucleon self energy through the sixth chiral order in the covariant chiral perturbation theory (PT) in the single baryon sector. The validity of the e…
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…
Analytic NNLO QCD corrections to top quark pair production in electron-positron collisions
Long-Bin Chen, Jian Wang, Yefan Wang
We present the analytic total cross section of top quark pair production in electron-positron annihilation at next-to-next-to-leading order (NNLO) in Quantum Chromodynamics (QCD).…
Two-loop electroweak corrections to the Higgs boson rare decay process
Zi-Qiang Chen, Long-Bin Chen, Cong-Feng Qiao +1
Recently, the ATLAS and CMS collaborations jointly announced the first evidence of the rare Higgs boson decay channel , with a ratio of times the leading orde…
NLO QCD corrections to the -pair hadroproduction
Zi-Qiang Chen, Long-Bin Chen, Cong-Feng Qiao
The meson pair, including pairs of pseudoscalar states and vector states, productions in proton-proton collisions are investigated at the next-to-leading order (NLO) accuracy…
