  1. 48. Endpoint factorization for inclusive semileptonic top quark decays in off-shell boosted top quark production
    Regner Christoph (University of Vienna)
    4/15/24, 9:30 AM

    In this talk we discuss a factorization for the $e^+e^-$ 2-jettiness distribution in the resonance region for boosted top quark pair production where the top quark descays semileptonically, and where we also measure leptonic distributions in the endpoint region where the bottom jet invariant mass is small. This multivariate distribution combines the known factorization theorems for inclusive...

  2. 49. Progress in Understanding Heavy Quark Fragmentation in the Transverse Plane
    Johannes Michel (University of Amsterdam, Institute of Physics)

    Talk

    I discuss ongoing progress in the understanding of heavy-quark transverse momentum-dependent (TMD) fragmentation functions (FFs). These advances include their explicit next-to-leading order calculation in massive SCET and bHQET, exposing a rich singularity structure that is also relevant for the extension of fixed-order subtraction schemes to quasi-collinear limits. I further present how many...

  3. 47. A Blueprint for Controlling the Monte-Carlo Top Quark Mass Scheme
    Andre Hoang (University of Vienna)
    4/15/24, 10:30 AM
    Talk

    To control the scheme of the Monte-Carlo (MC) top quark mass parameter several ingredients are mandatory, concerning the knowledge of the infrared dynamics of the top mass sensitive observable, the MC parton shower and the MC hadronization evolution. I discuss these ingredients and their interplay for the simple case of 2-jettiness for boosted top production in electron-positron annihilation,...
