Asymptotic charges in massless QED revisited: A view from Spatial Infinity
Miguel Campiglia, Alok Laddha
Hamada and Shiu have recently shown that tree level amplitudes in QED satisfy an infinite hierarchy of soft photon theorems, the first two of which are Weinberg and Low's theorems…
Scalar Asymptotic Charges and Dual Large Gauge Transformations
Miguel Campiglia, Laurent Freidel, Florian Hopfmüller +1
In recent years soft factorization theorems in scattering amplitudes have been reinterpreted as conservation laws of asymptotic charges. In gauge, gravity, and higher spin theories…
Null infinity, the BMS group and infrared issues
Abhay Ashtekar, Miguel Campiglia, Alok Laddha
There has been a recent resurgence of interest in the structure of the gravitational field at null infinity, sparked by new results on soft charges and infrared issues related to t…
