TF1 Snowmass Report: Quantum gravity, string theory, and black holes
Daniel Harlow, Shamit Kachru, Juan Maldacena +35
We give an overview of the field of quantum gravity, string theory and black holes summarizing various white papers in this subject that were submitted as part of the Snowmass proc…
Lectures on Celestial Holography
Ana-Maria Raclariu
These notes consist of 3 lectures on celestial holography given at the Pre-Strings school 2021. We start by reviewing how semiclassically, the subleading soft graviton theorem impl…
Scattering and the Celestial Torus
Alexander Atanasov, Adam Ball, Walker Melton +2
Analytic continuation from Minkowski space to split signature spacetime has proven to be a powerful tool for the study of scattering amplitudes. Here we show that, under th…
Celestial Amplitudes from UV to IR
Nima Arkani-Hamed, Monica Pate, Ana-Maria Raclariu +1
Celestial amplitudes represent 4D scattering of particles in boost, rather than the usual energy-momentum, eigenstates and hence are sensitive to both UV and IR physics. We show th…
Celestial Operator Products of Gluons and Gravitons
Monica Pate, Ana-Maria Raclariu, Andrew Strominger +1
The operator product expansion (OPE) on the celestial sphere of conformal primary gluons and gravitons is studied. Asymptotic symmetries imply recursion relations between products…
Conformally Soft Theorem in Gauge Theory
Monica Pate, Ana-Maria Raclariu, Andrew Strominger
Asymptotic particle states in four-dimensional celestial scattering amplitudes are labelled by their Lorentz/conformal weights rather than the usua…
