From Gross-Manes to Alday-Maldacena
Leonardo Pipolo de Gioia, Sabrina Pasterski, Pedro Vieira
Minimal surfaces govern the classical limit of several important observables in string theory. Two basic examples are the Gross--Manes saddle for high-energy string scattering in f…
Celestial Sector in CFT: Conformally Soft Symmetries
Leonardo Pipolo de Gioia, Ana-Maria Raclariu
We show that time intervals of width in 3-dimensional conformal field theories (CFT) on the Lorentzian cylinder admit an infinite dimensional symmetry enhancement in the l…
Eikonal Approximation in Celestial CFT
Leonardo Pipolo de Gioia, Ana-Maria Raclariu
We identify an eikonal regime in celestial CFT in which massless 2-2 scattering is dominated by t-channel exchange. We derive a formula for the celestial amplitude that resums…
Celestial Holography: Lectures on Asymptotic Symmetries
P. B. Aneesh, Geoffrey Compère, Leonardo Pipolo de Gioia +2
The aim of these Lectures is to provide a brief overview of the subject of asymptotic symmetries of gauge and gravity theories in asymptotically flat spacetimes as background mater…
