Room: Physics Department (Bldg. 510), Large Seminar Room We discuss important aspects of global PDF analyses beyond NNLO in QCD with emphasis on the impact of recent higher-order calculations that are part of the ingredients of recent approximate N^3LO PDF determinations. In particular, we discuss the role of heavy-quark mass treatments and DGLAP evolution at N^3LO in QCD.

Climbing the Spin Tower: Spinning Black Holes from Fixed-Spin Theories
- Manfred Kraus (IF-UNAM)
14:20 - 14:45
Room: Physics Department (Bldg. 510), Large Seminar Room In this talk, I present a new perspective on spinning black holes in which their classical dynamics emerges from a tower of fixed-spin theories. Starting from quantum amplitudes for massive particles with definite spin, we construct gravitational scattering amplitudes for each spin sector and study their classical limit. Remarkably, the structure of the amplitudes reveals that the dynamics of a Kerr black hole can be organized as a hierarchy of contributions associated with increasing powers of spin. By analyzing these sectors systematically, we obtain new results for binary black-hole dynamics at the third post-Minkowskian order and extend classical observables to quartic order in spin.
