Abstract The determination of the strong coupling constant $$\alpha _{\mathrm{s}} (m_{\mathrm{Z}})$$ α s ( m Z ) from H1 inclusive and dijet cross section data [1] exploits perturbative QCD predictions in next-to-next-to-leading order (NNLO) [2–4]

The partonic structure of the electron at the next-to-leading logarithmic accuracy in QED

Autor: V. Bertone, M. Cacciari, S. Frixione, G. Stagnitto

Publikováno v: Journal of High Energy Physics, Vol 2020, Iss 3, Pp 1-59 (2020)

Abstract By working in QED, we obtain the electron, positron, and photon Parton Distribution Functions (PDFs) of the unpolarised electron at the next-to-leading logarithmic accuracy. The PDFs account for all of the universal effects of initial-state

Shadow generalized parton distributions: a practical approach to the deconvolution problem of DVCS

Autor: V. Bertone, H. Dutrieux, C. Mezrag, H. Moutarde, P. Sznajder

Publikováno v: SciPost Physics Proceedings, Iss 8, p 107 (2022)

Deeply virtual Compton scattering (DVCS) attracts a lot of interest due to its sensitivity to generalized parton distributions (GPDs) which provide a rich access to the partonic structure of hadrons. However, the practical extraction of GPDs for t

Abstract We investigate the impact of displaced heavy-quark matching scales in a global fit. The heavy-quark matching scale $$\mu _{m}$$ μ m determines at which energy scale $$\mu $$ μ the QCD theory transitions from $$N_{F}$$ N F to $$N_{F}+1$$ N
