  2. 12. Novel approach to measure quark/gluon jets at the LHC
    Petr Baron (Palacky University (CZ))
    25/04/2023, 09:30

    In this talk, we present a new proposal on how to measure quark/gluon jet properties at the Large Hadron Collider (LHC). Our measurement strategy takes advantage of the fact that the LHC has collected data at different energies and focuses on measuring jet angularities. By studying these angularities, we aim to enrich statistically the given data sample by quark or gluon jets based on derived...

  3. 10. Lepton-hadron collisions in MadGraph5_aMC@NLO
    Manna Laboni
    25/04/2023, 09:50

    In the coming years, the Electron-Ion-Collider (EIC) in the United States will enable researchers to study lepton-hadron collisions with unprecedented precision. To consolidate figures of merit of a variety of measurements at the EIC, it is essential to include radiative corrections in simulations of electron-proton and electron-nucleus collisions. For the time being, there do not exist...

  4. 14. The new Alaric Parton Shower in Sherpa
    Daniel Reichelt (Durham University, IPPP)
    25/04/2023, 10:10

    I will present the logarithmically accurate parton shower Alaric. The algorithm is implemented in the Sherpa framework, and I show its NLL accuracy in final state evolution both numerically as well as by analytical agruments. I will also present phenomenological results compared to observables measured at LEP.

  5. 11. Photon splitting corrections to soft-photon resummation
    Lois Flower
    25/04/2023, 10:30

    In this talk I present an algorithm to add photon-splitting corrections
    to the Yennie-Frautschi-Suura-style soft-photon resummation available in
    the Sherpa Monte-Carlo event generator.
    Then, I introduce different lepton dressing strategies which incorporate
    further leptons and hadrons in addition to the customary photons,
    and discuss their sensitivity to dressing parameters such as...

  6. 7. Rivet, YODA and Contur: recent updates and ongoing developments
    Yoran Yeh (University College London (UK))
    26/04/2023, 09:00
  7. 8. Develpment of novel, portable Matrix Element + Phase Space methods
    Max Knobbe (University of Göttingen)
    26/04/2023, 09:20

    For more than a decade the current generation of fully automated,
    matrix element generators has provided hard scattering events with
    excellent flexibility and good efficiency. However, as recent studies
    have shown, they are a major bottleneck in the established Monte Carlo
    event generator toolchains. With the advent of the HL-LHC and ever
    rising precision requirements, future...

  8. 9. Jets and multiparton interactions in photon and proton collisions
    Juan Jose Castella
    26/04/2023, 09:40

    We present a study using a Rivet - including a new routine for low pT jet data - of the pythia 8 modelling of photoproduction (HERA), photon-photon (LEP) and proton-(antiproton) (LHC, Tevatron) jet measurements. We look the influence of the underlying event model, and its energy dependence.

  9. 13. Unweighting multijet event generation using factorisation-aware neural networks
    Timo Janssen
    26/04/2023, 10:00

    The generation of unit-weight events for complex scattering processes presents a severe challenge to modern Monte Carlo event generators. Even when using sophisticated phase-space sampling techniques adapted to the underlying transition matrix elements, the efficiency for generating unit-weight events from weighted samples can become a limiting factor in practical applications. Here we present...
