Impact of jet-production data on the next-to-next-to-leading-order determination of HERAPDF2.0 parton distributions / H1 Collaboration
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 jet data as published by the H1 and ZEUS collaborations.

The Large Hadron-Electron Collider at the HL-LHC / FCC-he Study Group Collaboration
The Large Hadron electron Collider, LHeC, is the means to move deep inelastic physics following HERA to the energy frontier of particle physics as it is being exploited by the HL-LHC. The paper presents a thorough update of the initial LHeC Conceptual Design Report (CDR) published in 2012. [...]

Second-order QCD corrections to event shape distributions in deep inelastic scattering / Gehrmann, T. (Zurich U.) ; Huss, A. (CERN) ; Mo, J. (Zurich U.) ; Niehues, J. (Durham U., IPPP)
We compute the next-to-next-to-leading order (NNLO) QCD corrections to event shape distributions and their mean values in deep inelastic lepton-nucleon scattering. The magnitude and shape of the corrections varies considerably between different variables. [...]

Calculations for deep inelastic scattering using fast interpolation grid techniques at NNLO in QCD and the extraction of $\alpha_s$ from HERA data / Britzger, D.

(Oxford U.) ; Huss, A. (CERN) ; Morgan, T. (Durham U., IPPP) ; Niehues, J. (Durham U., IPPP) ; Pires, J. (Lisbon, IST ; LIP, Lisbon) et al.
The extension of interpolation-grid frameworks for perturbative QCD calculations at next-to-next-to-leading order (NNLO) is presented for deep inelastic scattering (DIS) processes. A fast and flexible evaluation of higher-order predictions for any a posteriori choice of parton distribution functions (PDFs) or value of the strong coupling constant is essential in iterative fitting procedures to extract PDFs and Standard Model parameters as well as for a detailed study of the scale dependence.

Jet production in charged-current deep-inelastic scattering to third order in QCD / Gehrmann, T. (Zurich U.) ; Huss, A. (CERN) ; Niehues, J. (Durham U., IPPP) ; Vogt, A. (Liverpool U., Dept. Math.) ; Walker, D.M. (Durham U., IPPP)
The production of jets in charged-current deep-inelastic scattering (CC DIS) probes simultaneously the strong and the electroweak sectors of the Standard Model; its measurement provides important information on the quark flavour structure of the proton. We compute third-order (N3LO) perturbative QCD corrections to this process, fully differential in the jet and lepton kinematics. [...]

Dijet production in diffractive deep-inelastic scattering in next-to-next-to-leading order QCD / Britzger, D. (Heidelberg U.) ; Currie, J. (Durham U., IPPP) ; Gehrmann, T. (Zurich U.) ; Huss, A. (CERN) ; Niehues, J. (Durham U., IPPP) ; Žlebčík, R. (DESY)
Hard processes in diffractive deep-inelastic scattering can be described by a factorisation into parton-level subprocesses and diffractive parton distributions. In this framework, cross sections for inclusive dijet production in diffractive deep-inelastic electron-proton scattering (DIS) are computed to next-to-next-to-leading order (NNLO) QCD accuracy and compared to a comprehensive selection of data.

N$^{3}$LO corrections to jet production in deep inelastic scattering using the Projection-to-Born method / Currie, J. (Durham U., IPPP) ; Gehrmann, T. (Zurich U.) ; Glover, E.W.N. (Durham U., IPPP) ; Huss, A. (CERN) ; Niehues, J. (Durham U., IPPP) ; Vogt, A. (Liverpool U., Dept. Math.)
Computations of higher-order QCD corrections for processes with exclusive final states require a subtraction method for real-radiation contributions. We present the first-ever generalisation of a subtraction method for third-order (N3LO) QCD corrections. [...]

This talk discusses recent results for next-to-next-to-leading order (NNLO) QCD corrections to jet cross sections and transverse momentum distributions. The results are obtained in the NNLOJET code framework, which provides an implementation of the antenna subtraction method for the handling of infrared singular contributions at NNLO. [...]

Determination of the strong coupling constant $\alpha_s(M_Z)$ in next-to-next-to-leading order QCD using H1 jet cross section measurements / H1 Collaboration
The strong coupling constant $\alpha_s(M_Z)$ is determined from inclusive jet and dijet cross sections in neutral-current deep-inelastic $ep$ scattering (DIS) measured at HERA by the H1 collaboration using next-to-next-to-leading order (NNLO) QCD predictions. The dependence of the NNLO predictions and of the resulting value of $\alpha_s(M_Z)$ at the $Z$-boson mass $m_Z$ are studied as a function of the choice of the renormalisation and factorisation scales.
