    Workshop on Scattering Amplitude and Feynman Loop Integration for Gravitational Wave Physics

    → Europe/London
    4402 (James Clerk Maxwell Building)

    4402

    James Clerk Maxwell Building

    University of Edinburgh
    Description

    Quantum scattering amplitude methods have proven invaluable in many areas of physics, most recently in gravitational-wave physics. A key component of this progress has been improved algorithms for dealing with the encountered Feynman loop integrals. This focused workshop brings together leading experts in scattering amplitudes and Feynman loop integration to discuss the latest methods for efficiently constructing precision perturbative solutions for gravitational. This includes discussing recent developments in machine learning approaches. The workshop will consist of talks led by discussion leaders, followed by free discussion and working together to implement and test proposed solutions.
