DYTurbo: Fast predictions for Drell-Yan processes / Camarda, Stefano (CERN) ; Boonekamp, Maarten (Saclay) ; Bozzi, Giuseppe (INFN, Pavia ; Pavia U.) ; Catani, Stefano (INFN, Florence) ; Cieri, Leandro (INFN, Milan Bicocca) ; Cuth, Jakub (Mainz U.) ; Ferrera, Giancarlo (INFN, Milan ; Milan U.) ; de Florian, Daniel (San Martin Natl. U.) ; Glazov, Alexandre (DESY) ; Grazzini, Massimiliano (Zurich U.) et al.
Drell-Yan lepton pair production processes are extremely important for Standard Model (SM) precision tests and for beyond the SM searches at hadron colliders. Fast and accurate predictions are essential to enable the best use of the precision measurements of these processes; they are used for parton density fits, for the extraction of fundamental parameters of the SM, and for the estimation of background processes in searches.

Fiducial perturbative power corrections within the q$_{\bf T}$ subtraction formalism / Camarda, Stefano (CERN) ; Cieri, Leandro (Valencia U., IFIC) ; Ferrera, Giancarlo (Milan U. ; INFN, Milan)
We consider higher-order QCD corrections to the production of high-mass systems in hadron collisions within the transverse-momentum (q$_{\rm T}$) subtraction formalism. We present a method to consistently remove the linear power corrections in q$_{\rm T}$ which appears when fiducial kinematical cuts are applied on the final state system. [...]

Drell-Yan lepton-pair production: $q_T$ resummation at N$^3$LL accuracy and fiducial cross sections at N$^3$LO / Camarda, Stefano (CERN) ; Cieri, Leandro (INFN, Florence) ; Ferrera, Giancarlo (INFN, Milan)
We present high-accuracy QCD predictions for the transverse-momentum ($q_T$) distribution and fiducial cross sections of Drell-Yan lepton pairs produced in hadronic collisions. At small value of $q_T$ we resum to all perturbative orders the logarithmically enhanced contributions up to next-to-next-to-next-to-leading logarithmic (N$^3$LL) accuracy, including all the next-to-next-to-next-to-leading order (N$^3$LO) (i.e. [...]

Higgs boson production at the LHC: fast and precise predictions in QCD at higher orders / Camarda, Stefano (CERN) ; Cieri, Leandro (Valencia U., IFIC) ; Ferrera, Giancarlo (Milan U. ; INFN, Milan) ; Urtasun-Elizari, Jesus (Milan U. ; INFN, Milan)
We present a new numerical program, HTurbo, which provides fast and numerically precise predictions for Higgs boson production cross sections. The present version of the code implements the perturbative QCD expansion up to the next-to-next-to-leading order also combined with the resummation of the large logarithmic corrections at small transverse momenta up to next-to-next-to-leading logarithmic accuracy and it includes the Higgs boson production through gluon fusion and decay in two photons with the full dependence on the final-state kinematics.

NNLOPS accurate Drell-Yan production / Karlberg, Alexander (Oxford U., Theor. Phys.) ; Re, Emanuele (Oxford U., Theor. Phys.) ; Zanderighi, Giulia (CERN)
We present a next-to-next-to-leading order accurate description of Drell-Yan lepton pair production processes through $\gamma^*/Z$ or $W$ exchange that includes consistently parton shower effects. Results are obtained by upgrading the vector-boson plus one jet NLO calculation in POWHEG with the MiNLO procedure and by applying an appropriate reweighting procedure making use of the DYNNLO program.

The path to $\hbox {N}^3\hbox {LO}$ parton distributions / NNPDF Collaboration
We extend the existing leading (LO), next-to-leading (NLO), and next-to-next-to-leading order (NNLO) NNPDF4.0 sets of parton distribution functions (PDFs) to approximate next-to-next-to-next-to-leading order (aN$^3$LO). We construct an approximation to the N$^3$LO splitting functions that includes all available partial information from both fixed-order computations and from small and large $x$ resummation, and estimate the uncertainty on this approximation by varying the set of basis functions used to construct the approximation.

MiNNLO$_{\text{PS}}$: A new method to match NNLO QCD to parton showers / Monni, Pier Francesco (CERN) ; Nason, Paolo (INFN, Milan Bicocca ; Milan Bicocca U.) ; Re, Emanuele (CERN ; Annecy, LAPTH) ; Wiesemann, Marius (CERN ; Munich, Max Planck Inst.) ; Zanderighi, Giulia (Munich, Max Planck Inst.)
We present a novel method to combine QCD calculations at next-to-next-to-leading order (NNLO) with parton shower (PS) simulations, that can be applied to the production of heavy systems in hadronic collisions, such as colour singlets or a $t\bar{t}$ pair. The NNLO corrections are included by connecting the MiNLO$^\prime$ method with transverse-momentum resummation, and they are calculated at generation time without any additional reweighting, making the algorithm considerably efficient.

Momentum-space resummation for transverse observables and the Higgs $p_\perp$ at N$^3$LL+NNLO / Bizon, Wojciech (Oxford U., Theor. Phys.) ; Monni, Pier Francesco (CERN) ; Re, Emanuele (CERN ; Annecy, LAPTH) ; Rottoli, Luca (Oxford U., Theor. Phys.) ; Torrielli, Paolo (Turin U. ; INFN, Turin)
We present an approach to the momentum-space resummation of global, recursive infrared and collinear safe observables featuring kinematic zeros away from the Sudakov limit. In the hadro-production of a generic colour singlet, we consider the family of inclusive observables which do not depend on the rapidity of the radiation, prime examples being the transverse momentum of the singlet, and $\phi^*$ in Drell-Yan pair production.

Next-to-leading power two-loop soft functions for the Drell-Yan process at threshold / Broggio, Alessandro (Milan Bicocca U. ; INFN, Milan Bicocca) ; Jaskiewicz, Sebastian (Durham U., IPPP) ; Vernazza, Leonardo (CERN ; Turin U. ; INFN, Turin)
We calculate the generalized soft functions at $\mathcal{O}(\alpha_s^2)$ at next-to-leading power accuracy for the Drell-Yan process at threshold. The operator definitions of these objects contain explicit insertions of soft gauge and matter fields, giving rise to a dependence on additional convolution variables with respect to the leading power result.
