  14. 36. The full angle-dependence of the four-loop cusp anomalous dimension in QED
    Robin Brüser (University Siegen)
    10/7/20, 11:10 AM

    The cusp anomalous dimension is a ubiquitous quantity in gauge theories such as QCD and QED. It governs the infrared behaviour of scattering amplitudes and is a universal ingredient in heavy quark effective theory and soft collinear effective theory. In this talk I present new results for the full angle-dependence of the fermionic quartic Casimir contributions at four loops. These are the...

  15. 37. NLO QCD-EW corrections to Higgs boson gluon fusion
    Marco Bonetti (RWTH)
    10/7/20, 11:28 AM

    The study of the Higgs boson properties is one of the main
    tasks of contemporary high-energy physics. Among Higgs properties, its interaction with gluons is interesting since it can be facilitated by yet unknown elementary particles. At present, one of the major sources of uncertainty in the theoretical description of ggH coupling originates from mixed QCD-electroweak contributions. I will...

  16. 38. The Kinetic Heavy Quark Mass to Three Loop
    Kay Schoenwald (KIT)
    10/7/20, 11:46 AM

    We compute three-loop corrections to the relation between the heavy quark masses defined in the pole and kinetic schemes. Using known relations between the pole and $\overline{\rm MS}$ quark masses we can establish precise relations between the kinetic and $\overline{\rm MS}$
    charm and bottom masses. As compared to two loops, the precision is improved by a factor two to three. Our results...

  17. 40. On the status of the heavy quark expansion for charmed hadrons
    Daniel Moreno (University of Siegen)
    10/7/20, 12:04 PM

    The heavy quark expansion (HQE), which provides a perturbative expansion in the inverse heavy quark mass, has proven to be very successful for describing bottomed hadrons. However, its applicability has often been questioned for charmed hadrons due to the charm quark is actually not so heavy. In this talk we revisit the status of the HQE for charm. In particular, we study pseudoscalar...

  18. 39. Automating the calculation of jet functions in SCET
    Kevin Brune (University of Siegen)
    10/7/20, 12:22 PM

    In pertubative QCD large logarithms can arise in the computation of collider observables. These logarithms can be resummed via factorization theorems within Soft-Collinear Effective Theory(SCET). The
    factorization theorems contain jet functions, which describe collinear interactions.
    In this talk I present a systematic framework for the computation of jet functions for generic observables....

  27. 43. Probing New Physics in b \to d Transitions
    Aleksey Rusov (University of Siegen)
    10/7/20, 5:55 PM

    Recent experimental data on several observables in semileptonic $B$-meson decays are found to be in tension with the corresponding Standard Model predictions. Most of these deviations are related to $b \to c$ and $b \to s$ flavour changing transitions. In this talk, I plan to discuss possible New Physics effects in $b \to d \mu^+ \mu^-$ flavour changing neutral currents.
    These NP contributions...

  28. 42. Contribution of the Darwin operator to non-leptonic decays of heavy quarks
    Maria Piscopo
    10/7/20, 6:13 PM

    The total decay width of heavy hadrons can be systematically computed using the Heavy Quark Expansion (HQE) framework, as a series in inverse powers of the heavy quark mass m_Q. Computation of higher corrections is crucial both to test the consistency of HQE itself and to constrain the size of possible new physics effects. In this talk I will present the result of our recent paper on the...
