Constraining liberated supergravity

چکیده
Fermionic terms in a class of locally supersymmetric theories called "liberated supergravity" are nonrenormalizable interactions proportional to inverse powers the supersymmetry breaking scale and Planck mass. This property defines an intrinsic cutoff for liberated supergravities, which therefore effective valid only below energies that never exceed cutoff. Requiring exceeds current theoretical observational bounds shows new scalar potential allowed by supergravity can neither change cosmological constant predicted any observable amount, nor give measurable contributions particle masses. We show it is nevertheless possible define simple model slow roll inflation up energy scales well above Hubble parameter during limits after inflation. The key constructing viable scale, from Planck-scale value inflation, TeV-scale

Constraining higher derivative supergravity with scattering amplitudes
Supersymmetry constraints on higher derivative couplings in maximal supergravity theories have been investigated extensively in the past [1–7] and have led to remarkable exact results on the quantum effective action of string theory. The method of Refs. [3,8–10] in obtaining constraints on higher derivative terms in gauge and gravity theories with maximal supersymmetry was by explicitly analyzi...
متن کاملFrom Trapped Atoms to Liberated Quarks
The QCD phase diagram contains several strongly interacting quantum gases or liquids. Experiments at the Relativistic Heavy Ion Collider (RHIC) indicate that at temperatures close to the critical temperature Tc the quark gluon plasma is strongly interacting. The strongly interacting plasma (sQGP) is characterized by a very small viscosity to entropy ratio and by its large opacity for high energ...
متن کاملHalf-liberated Real Spheres and Their Subspaces
We describe the quantum subspaces of Banica-Goswami’s half-liberated real-spheres, showing in particular that there is a bijection between the symmetric ones and the conjugation stable closed subspaces of the complex projective spaces.
متن کاملSemirigid supergravity.
We formulate two-dimensional topological gravity starting from local N = 2 superconformal geometry. The theory is free from the very beginning. The usual ‘‘twisting’’ of the N = 2 algebra emerges from symmetry breaking when we expand about a nonzero value for one of the ghost fields. The mysterious linear term in the supercurrent emerges automatically, as does a full superfield formalism for th...
متن کاملChiral Supergravity
We study the linearized approximation of N = 1 topologically massive supergravity around AdS3. Linearized gravitino fields are explicitly constructed. For appropriate boundary conditions, the conserved charges demonstrate chiral behavior, so that chiral gravity can be consistently extended to chiral supergravity.
