Final Project Report for DOE Grant NO.: DE-SC0010534 Period: Sept 2013-March 31, 2016

Abstract

Higher spin theories has been an active area of research in recent years. One of the main research activities of the PI Murat Gunaydin over the period of this grant has been the application of quasiconformal methods to construct and study higher spin (HS) algebras and superalgebras in various dimensions. Over the past decade work on amplitudes in gauge theories, supergravity and string theories has been a very active area of research. Enormous progress has been made in the understanding of the structure of amplitudes in these theories. The novel methods and results obtained have made it possible to do calculations in gauge theories and supergravity theories that go well beyond the calculations one can do using the old fashioned Feynman diagram techniques. Work on amplitudes in matter coupled supergravity theories has been the second main focus of the PI during the funding period. The previous work of the PI on supergravity theories has played a fundamentally important role in the current work on amplitudes.
