Non-compact gauge groups, tensor fields and Yang-Mills-Einstein amplitudes
Marco Chiodaroli, Murat Gunaydin, Henrik Johansson +1
Scattering amplitudes in Yang-Mills-Einstein theories have been investigated mostly for compact gauge groups. While non-compact gauge groups are not physically viable in Yang-Mills…
Spinor-helicity formalism for massive and massless amplitudes in five dimensions
Marco Chiodaroli, Murat Gunaydin, Henrik Johansson +1
Five-dimensional gauge and gravity theories are known to exhibit striking properties. D=5 is the lowest dimension where massive tensor states appear naturally, providing a testing…
Unified non-metric (1,0) tensor-Einstein supergravity theories and (4,0) supergravity in six dimensions
Murat Gunaydin
The ultrashort unitary (4,0) supermultiplet of 6d superconformal algebra OSp(8*|8) reduces to the CPT-self conjugate supermultiplet of 4d superconformal algebra SU(2,2|8) that repr…
Explicit Formulae for Yang-Mills-Einstein Amplitudes from the Double Copy
Marco Chiodaroli, Murat Gunaydin, Henrik Johansson +1
Using the double-copy construction of Yang-Mills-Einstein theories formulated in our earlier work, we obtain compact presentations for single-trace Yang-Mills-Einstein tree amplitu…
Exceptional F(4) Higher-Spin Theory in AdS(6) at One-Loop and other Tests of Duality
Murat Gunaydin, E. D. Skvortsov, Tung Tran
We study the higher-spin gauge theory in six-dimensional anti-de Sitter space that is based on the exceptional Lie superalgebra . The relevant higher-spin algebra was…
Non-associativity in non-geometric string and M-theory backgrounds, the algebra of octonions, and missing momentum modes
Murat Gunaydin, Dieter Lust, Emanuel Malek
We propose a non-associative phase space algebra for M-theory backgrounds with locally non-geometric fluxes based on the non-associative algebra of octonions. Our proposal is based…
