Loop Corrections to Cosmological Correlators / Anastasiou, Charalampos (speaker)
Surveys of the Large Scale Structure are becoming increasingly detailed. A primary theoretical tool for analyzing this data and constraining cosmological models is the Effective Field Theory (EFT) of Large Scale Structure. [...]

Special Functions for Five-Point One-Mass Scattering in QCD / Sotnikov, Vasily (speaker) (University of Zurich (UZH))
I will present the recent computation of a complete set of the two-loop five-point Feynman integrals with one external mass. Employing the method of canonical differential equations and the properties of Chen's iterated integrals, we construct a basis of special functions that greatly facilitates the calculation of scattering amplitudes, and is amenable for applications in NNLO QCD phenomenology.

Multi-Leg Amplitudes in QCD / Zoia, Simone (speaker)
I review the recent advances in the computation of QCD scattering amplitudes at the high multiplicity frontier. Their computation is hindered by both algebraic and analytic complexity, making them one of the main bottlenecks to obtaining predictions at the next to-next-to-leading order in QCD for many interesting LHC processes. [...]

QCD in the Cores of Neutron Stars / Kurkela, Eero Aleksi (speaker)
Gravity meets QCD in a very concrete way in neutron stars. Their cores contain ultra-dense hadronic matter whose densities reach as high as those realized in ultrarelativistic heavy-ion collisions at the LHC. [...]

Fundamental Physics and Gravitational Waves / Sturani, Riccardo (speaker) (IFT-UNESP/ICTP-SAIFR)
The detections of gravitational waves emitted by compact binary coalescences gave rise to the new science of Gravitational Wave Astronomy, which opened up new possibilities for scientific investigation also in cosmology and fundamental physics. In this presentation I will give an overview of the observational results and some hints to the impact they had, are having and will have on our understanding of fundamental physics, with emphasis on the analytic modeling of the General Relativistic two-body problem..

Absorptive Effects and Classical Black Hole Scattering / Jones, Callum (speaker)
I will describe an approach to incorporating absorption effects into the post-Minkowskian effective description of two-body classical gravitational scattering. By coupling the usual point-particle effective description to an invisible sector of gapless internal degrees-of-freedom, the leading-order absorptive effects are encoded in the low-energy expansion of a spectral density function; for black holes this spectral function is obtained by matching an absorption cross-section calculated in black hole perturbation theory.

Spinning Waveforms from KMOC at Leading Order / Novichkov, Pavel (speaker)
I present a method for computing gravitational waveforms from singularities of the five-point amplitude. The procedure is based on the KMOC formalism and leverages the analytic properties of amplitudes in the complex plane. [...]

Aspects of Conformal Gravity and Double Field Theory from a Double Copy of Yang-Mills Theory / Menezes, Gabriel (speaker)
Double field theory can be naturally constructed as the double copy of a Yang-Mills theory. Indeed, a double copy prescription for the Yang-Mills action can be provided that produces a double field theory action in which the dilaton has been integrated out. [...]

Double Copies from Recursion / Patatoukos, Kokkimidis (speaker)
I discuss expressions for gravity amplitudes and show that they can be written as term wise double copies of those in YM gauge theory derived from BCFW..
