This review describes the duality between color and kinematics and its applications, with the
aim of gaining a deeper understanding of the perturbative structure of gauge and gravity …

The post-Minkowskian expansion of Einstein's general theory of relativity has received much
attention in recent years due to the possibility of harnessing the computational power of …

Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

We provide an overview of the string landscape and the Swampland program. Our review of
the string landscape covers the worldsheet and spacetime perspectives, including vacua …

A bstract We compute classical gravitational observables for the scattering of two spinless
black holes in general relativity and\(\mathcal {N}\)= 8 supergravity in the formalism of …

Providing a comprehensive, pedagogical introduction to scattering amplitudes in gauge
theory and gravity, this book is ideal for graduate students and researchers. It offers a …

A bstract We use\(\mathcal {N}\)= 8 supergravity as a toy model for understanding the
dynamics of black hole binary systems via the scattering amplitudes approach. We compute …

A bstract Recently, a perturbative duality between gauge and gravity theories (the double
copy) has been discovered, that is believed to hold to all loop orders. In this paper, we …

We give a comprehensive review of recent developments on using the pure spinor
formalism to compute massless superstring scattering amplitudes at tree level. The main …

Outlining a revolutionary reformulation of the foundations of perturbative quantum field
theory, this book is a self-contained and authoritative analysis of the application of this new …
