  1. 19. Absolute mass threshold resummation for the production of four top quarks
    Laura Moreno Valero (University of Münster)
    10/25/23, 9:30 AM
    Talk

    In this talk we present results for soft gluon resummation applied to the production of four top quarks in the absolute mass threshold limit. The theoretical predictions at NLO, including a full set of strong and electroweak NLO corrections, yield a relatively large error due to scale variation. We compute the resummed cross section at next-to-leading logarithmic (NLL$^\prime$) accuracy,...

  2. 25. Associated production of heavy quarkonia and D mesons in the high-energy factorization
    Vladimir Saleev (Samara University)
    10/25/23, 9:55 AM
    Talk

    We study associated production of heavy quarkonia and D mesons in the improved color evaporation model using the high-energy factorization as it is formulated in the parton Reggeization approach. The last one is based on the modified Kimber-Martin-Ryskin-Watt model for unintegrated parton distribution functions and the effective field theory of Reggezied gluons and quarks, suggested by L.N....

  3. 33. Full top-quark mass dependence in diphoton production at NNLO in QCD
    Federico Ripani (Università di Roma “La Sapienza” and INFN Sezione di Roma)
    10/25/23, 10:50 AM
    Talk

    I will present the Next-to-next-to-leading order QCD massive corrections,
    induced by a loop of top quarks, to di-photon production in proton-proton
    collisions. This process is very important as a test of perturbative QCD
    and as a background process for the decay of a Higgs into two photons.
    All the involved partonic subprocesses are taken into account; in
    particular the quark-antiquark...

  4. 40. Measurement of the top-quark mass with the ATLAS experiment in 13 TeV pp collision data.
    Javier Jiménez Peña (IFAE Barcelona)
    10/25/23, 11:15 AM
    Talk

    The measurement of the top-quark mass in top-quark pair production using the full Run 2 dataset collected with the ATLAS experiment at √s = 13 TeV will be presented. This measurement is carried out in the dilepton channel using a template method. The talk will have a special emphasis on the theoretical uncertainties affecting experimental measurements of the top-quark mass, as more and more...

  5. 23. Automatic Computation of the Soft Anomalous Dimension Matrices for the Heavy-Quark Hadroproduction
    Bakar Chargeishvili (University of Hamburg)
    10/25/23, 11:40 AM
    Talk

    In this work we present the tools developed for the automatization of the calculation of the soft anomalous dimension matrices for the heavy-quark hadroproduction processes at one- and two-loop accuracy in QCD. The foundation of this procedure is the construction of orthogonal color basis for $2 \rightarrow n$ processes which will also be discussed. The application of these tools is...
