  1. 84. Flavor thresholds and quark-mass effects in the Collins-Soper kernel (aka the rapidity anomalous dimension)
    Peter Plößl (Deutsches Elektronen-Synchrotron DESY)
    4/18/24, 11:30 AM
    Talk

    We discuss the treatment of finite charm and bottom quark mass effects in the Collins-Soper kernel or equivalently the rapidity anomalous dimension. In particular, we derive a consistent flavor matching relation with different numbers of active flavors. This allows us to properly separate the perturbative contributions due to heavy quarks from the remaining $n_F = 3$ massless contributions....

  2. 85. The structure of quark mass corrections in double Higgs production amplitudes
    Sebastian Jaskiewicz (University of Bern)
    4/18/24, 12:00 PM
    Talk

    The leading and next-to-leading order QCD predictions for Higgs boson pair production at hadron colliders suffer from a large mass renormalisation scheme uncertainty related to the choice of the top quark mass. In this talk, I will discuss how the Method of Regions and factorisation in SCET can be utilised to understand the dependence of the result on the value of the intermediate quark mass...

  3. 86. SCET and bHQET matching coefficients and jet functions in the large-$\beta_0$ limit
    Mr Néstor González Gracia (University of Valencia/IFIC)
    4/18/24, 12:30 PM
    Talk

    We present a systematic approach for computing and analyzing of non-cusp and cusp perutvative series. The approach facilitates the extraction of renormalon divergences, the corresponding series ambiguity and the relation to non-perturbative power corrections. We applied it to the matching coefficients of QCD onto SCET and of (massive) SCET onto bHQET, as well as to the jet functions in both...
