11D Supergravity as a Gauge Theory for the M-Algebra
The eleven-dimensional gravitational action invariant under local Poincaré transformations is given by the dimensional continuation of the Euler class of ten dimensions. Here we show that the supersymmetric extension of this action leads, through the Noether procedure, to a theory with the local symmetry group given by the M-algebra. The fields of the theory are the vielbein eμ, the Lorentz (sp...
متن کاملConsistent nonlinear KK reduction of 11d supergravity on AdS7 × S4 and self-duality in odd dimensions
We show that there exists a consistent truncation of 11 dimensional supergravity to the ’massless’ fields of maximal (N=4) 7 dimensional gauged supergravity. We find the complete expressions for the nonlinear embedding of the 7 dimensional fields into the 11 dimensional fields, and check them by reproducing the d=7 susy transformation laws from the d=11 laws in various sectors. In particular we...
متن کاملSupergravity at Colliders
We consider supersymmetric theories where the gravitino is the lightest superparticle (LSP). Assuming that the long-lived next-to-lightest superparticle (NSP) is a charged slepton, we investigate two complementary ways to prove the existence of supergravity in nature. The first is based on the NSP lifetime which in supergravity depends only on the Planck scale and the NSP and gravitino masses. ...
متن کاملMicroprocessor controller for EL-11D ellipsometer
The purpose of the microprocessor – based controller described in the present study is to enable the measurements by means of EL-11D ellipsometer system to be carried in automatic mode. The geometry of optic components of the ellipsometer system can be changed in MANUAL and AUTOMATIC modes by means of the controller. Three keys incorporated on the front panel are used for setting of the ellipso...
متن کاملConsistency between 11d and U-duality
U duality transformations must act on a basis of states that form complete multiplets of the U group, at any coupling, even though the states may not be mass degenerate, as for a broken symmetry. Similarly, if superstring theory is related to a non-perturbative 11D M-theory, then an 11D supermultiplet structure is expected, even though the multiplet may contain states of different masses. We an...
