    Workshop on Feynman Integrals for Gravitational Waves

    → Europe/London
    Description

    Gravitational Wave Physics at LIGO-Virgo-KAGRA and future detectors requires precision predictions of inspiral waveforms for black hole and neutron star merger events. Given recent works that use quantum field theory methods based on scattering amplitudes or worldlines to understand the binary problem in general relativity, the evaluation of high-loop Feynman integrals becomes crucial for pushing the frontiers. This workshop brings together experts to discuss various aspects of Feynman integrals and their applications to gravitational physics, including integration-by-parts (IBP) reduction, differential equations, computational algebraic geometry, machine learning, and automation. The workshop also aims to identify state-of-the-art problems that require future efforts.
