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…
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…
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…
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…
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…
