Abstract We present a general subtraction scheme for NNLO calculations in massless QCD: the colourful antenna subtraction method. It is a reformulation of the antenna subtraction approach designed to address some of the limitations of the traditional

Abstract We compute next-to-next-to-leading order (NNLO) QCD corrections to neutral vector boson production in association with a charm jet at the LHC. This process is studied in the forward kinematics at $$\sqrt{s}=13$$ s = 13 TeV, which may provide

Abstract Fast interpolation-grid frameworks facilitate an efficient and flexible evaluation of higher-order predictions for any choice of parton distribution functions or value of the strong coupling $$\alpha _{\mathrm {s}}$$ α s . They constitute a

NNLO QCD corrections in full colour for jet production observables at the LHC

Autor: X. Chen, T. Gehrmann, E. W. N. Glover, A. Huss, J. Mo

Publikováno v: Journal of High Energy Physics, Vol 2022, Iss 9, Pp 1-32 (2022)

Abstract Calculations for processes involving a high multiplicity of coloured particles often employ a leading colour approximation, where only the leading terms in the expansion of the number of colours N c and the number of flavours n f are retaine

Abstract The HERAPDF2.0 ensemble of parton distribution functions (PDFs) was introduced in 2015. The final stage is presented, a next-to-next-to-leading-order (NNLO) analysis of the HERA data on inclusive deep inelastic ep scattering together with je
