Higgs Boson Pair Production via Gluon Fusion: Higher-Order Corrections and Theoretical Uncertainties
Ajjath A H, Simone Alioli, Emanuele Bagnaschi +51
In this contribution, the higher-order QCD and electroweak corrections to Standard Model Higgs boson pair production via the gluon-fusion mechanism, , are summarized and…
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…
