    Learning non-Higgsable gauge groups in 4D F-theory

    We apply machine learning techniques to solve a specific classification problem in 4D F-theory. For a divisor D on a given complex threefold base, we want to read out the non-Higgsable gauge group on it using loc...

    Singly-spinning black rings in D = 5 U(1)3 supergravity

    We construct black ring solutions in five-dimensional U(1)3 supergravity which carry three dipole charges, three electric charges and one angular momentum parameter. These solutions are written in a form that is ...

    NNLO hard functions in massless QCD

    We derive the hard functions for all 2 → 2 processes in massless QCD up to next-to-next-to-leading order (NNLO) in the strong coupling constant. By employing the known one- and two-loop helicity amplitudes for...
