Gauge-fixing local H symmetry in supergravities

Blog Article

Abstract We discuss known maximal D-dimensional supergravities of two types: type I with G/H coset spaces and type II derived by compactification from higher dimensions without dualization, these have less manifest symmetries.In 4D and 6D in type I models we perform explicit gauge-fixing of local H symmetries in unitary Bracelet gauges: symmetric, Iwasawa and partial Iwasawa.In 4D supergravity I in symmetric gauge global H-invariance and nonlinearly realized G-symmetry are valid on shell, classically.The global H-symmetry and G-symmetry in Iwasawa-type gauges in type I and in type II supergravities are not manifest, if at all present.

This fact raises the issue of the gauge AEG DIE6180HM 100cm Island Hood in Stainless Steel equivalence of the S-matrix of various gauge-fixed D-dimensional supergravities and its relation to the ones computable using superamplitude methods.
