Infinite-Dimensional Fermionic Symmetry in Supersymmetric Gauge Theories
Thomas T. Dumitrescu, Temple He, Prahar Mitra +1
We establish the existence of an infinite-dimensional fermionic symmetry in four-dimensional supersymmetric gauge theories by analyzing semiclassical photino dynamics in abelian ${…
Magnetic Corrections to the Soft Photon Theorem
Andrew Strominger
The soft photon theorem, in its standard form, requires corrections when the asymptotic particle states carry magnetic charges. These corrections are deduced using electromagnetic…
New Symmetries of QED
Daniel Kapec, Monica Pate, Andrew Strominger
The soft photon theorem in U(1) gauge theories with only massless charged particles has recently been shown to be the Ward identity of an infinite-dimensional asymptotic symmetry g…
Fast plunges into Kerr black holes
Shahar Hadar, Achilleas P. Porfyriadis, Andrew Strominger
Most extreme-mass-ratio-inspirals of small compact objects into supermassive black holes end with a fast plunge from an eccentric last stable orbit. For rapidly rotating black hole…
2D Kac-Moody Symmetry of 4D Yang-Mills Theory
Temple He, Prahar Mitra, Andrew Strominger
Scattering amplitudes of any four-dimensional theory with nonabelian gauge group may be recast as two-dimensional correlation functions on the asymptotic two-sphere at…
Higher-Dimensional Supertranslations and Weinberg's Soft Graviton Theorem
Daniel Kapec, Vyacheslav Lysov, Sabrina Pasterski +1
Asymptotic symmetries of theories with gravity in d=2m+2 spacetime dimensions are reconsidered for m>1 in light of recent results concerning d=4 BMS symmetries. Weinberg's soft gra…
