NLL resummation of one-jettiness for -boson plus jet production at hadron colliders
Simone Alioli, Guido Bell, Georgios Billis +7
We present the resummation of one-jettiness for the colour-singlet plus jet production process at hadron colliders up to the fou…
Rational Q-systems at Root of Unity I. Closed Chains
Jue Hou, Yunfeng Jiang, Yuan Miao
The solution of Bethe ansatz equations for XXZ spin chain with the parameter being a root of unity is infamously subtle. In this work, we develop the rational -system for th…
Evolution and interpolation of double parton distributions using Chebyshev grids
Markus Diehl, Riccardo Nagar, Peter Ploessl +1
Double parton distributions are the nonperturbative ingredients needed for computing double parton scattering processes in hadron-hadron collisions. They describe a variety of corr…
Refining the GENEVA method for Higgs boson production via gluon fusion
Simone Alioli, Georgios Billis, Alessandro Broggio +6
We describe a number of improvements to the GENEVA method for matching NNLO calculations to parton shower programs. In particular, we detail changes to the resummed calculation use…
Double Higgs production at NNLO interfaced to parton showers in GENEVA
Simone Alioli, Georgios Billis, Alessandro Broggio +6
In this work, we study the production of Higgs boson pairs at next-to-next-to-leading order in QCD matched to parton showers, using the \textsc{Geneva} framework and working in the…
Quark mass effects in double parton distributions
Markus Diehl, Riccardo Nagar, Peter Plößl
Double parton distributions can be computed from the perturbative splitting of one parton into two if the distance between the two observed partons is small. We develop schemes to…
ChiliPDF: Chebyshev Interpolation for Parton Distributions
Markus Diehl, Riccardo Nagar, Frank J. Tackmann
Parton distribution functions (PDFs) are an essential ingredient for theoretical predictions at colliders. Since their exact form is unknown, their handling and delivery for practi…
production at NNLO+PS accuracy in GENEVA
Thomas Cridge, Matthew A. Lim, Riccardo Nagar
We present an event generator for the process at next-to-next-to-leading order (NNLO) in QCD and matched to the PYTHIA8 parton shower. The calculation makes use…
Next-to-next-to-leading order event generation for boson pair production matched to parton shower
Simone Alioli, Alessandro Broggio, Alessandro Gavardi +4
We present a novel next-to-next-to-leading order (NNLO) QCD calculation matched to parton shower for the production of a pair of bosons decaying to four massless leptons, $p p…
Matching NNLO to parton shower using NLL colour-singlet transverse momentum resummation in GENEVA
Simone Alioli, Christian W. Bauer, Alessandro Broggio +6
We extend the GENEVA Monte Carlo framework using the transverse momentum of a colour-singlet system as the resolution variable. This allows us to use next-to-next-to-next-to leadin…
Prospects for quarkonium studies at the high-luminosity LHC
Emilien Chapon, David d'Enterria, Bertrand Ducloue +48
Prospects for quarkonium-production studies accessible during the upcoming high-luminosity phases of the CERN Large Hadron Collider operation after 2021 are reviewed. Current exper…
Precise predictions for photon pair production matched to parton showers in GENEVA
Simone Alioli, Alessandro Broggio, Alessandro Gavardi +5
We present a new calculation for the production of isolated photon pairs at the LHC with NNLL+NNLO accuracy. This is the first implementation within the GENEVA M…
Resummed predictions for hadronic Higgs boson decays
Simone Alioli, Alessandro Broggio, Alessandro Gavardi +5
We present the NNLL resummed -jettiness distribution for decays of the Standard Model Higgs boson to a -quark pair and to gluons. The calculation exploits a factori…
Efficient interpolation and evolution of parton distribution functions
Riccardo Nagar
We present an efficient numerical solution of the DGLAP equations for single and double parton distribution functions (PDFs and DPDs), based on the Chebyshev interpolation of these…
Factorisation of soft gluons in multiparton scattering
Markus Diehl, Riccardo Nagar
We show that soft gluons exchanged between the two colliding protons in multiparton scattering processes can be decoupled, such that their effects are described by the vacuum expec…
