Scattering amplitudes in affine gravity

چکیده
Affine gravity is a connection-based formulation of that does not involve metric. After review basic properties affine gravity, we compute the tree-level scattering amplitude scalar particles interacting gravitationally via connection in curved spacetime. We find that, while classically equivalent to general relativity, differs from metric quantum gravity.

Scattering amplitudes in Lifshitz spacetime
We consider the calculation of scattering amplitudes in field theories dual to Lifshitz spacetimes. These amplitudes provide an interesting probe of the IR structure of the field theory; our aim is to use them to explore the observable consequences of the singularity in the spacetime. We assume the amplitudes can be related by T-duality to a Wilson loop, as in the AdS case, and determine the bu...
متن کاملQuantum Affine Symmetry and Scattering Amplitudes of the Imaginary Coupled d ( 3 ) 4 Affine Toda Field Theory Gábor
An exact S-matrix is conjectured for the imaginary coupled d (3) 4 affine Toda field theory, using the U q (g (1) 2) symmetry. It is shown that this S-matrix is consistent with the results for the case of real coupling using the breather-particle correspondence. For q a root of unity it is argued that the theory can be restricted to yield Φ(11|14) perturbations of W A 2 minimal models and the r...
متن کاملHELICITY AND PLANAR AMPLITUDES IN PION-PROTON SCATTERING AT 6.0 GeV/c
In addition to optimal conditions, invariant laws of Lorentz, parity and time reversal are imposed to find the relation between observables (spin rotation parameters) and bilinear combination of helicity amplitudes in pion-proton elastic scattering at 6.0 GeV/c. By normalizing the differential cross-section to unity, the magnitudes of helicity amplitudes and the angle between them are dete...
متن کاملGravity Amplitudes from n-Space
We identify a hidden GL(n,C) symmetry of the tree level n-point MHV gravity amplitude. Representations of this symmetry reside in an auxiliary n-space whose indices are external particle labels. Spinor helicity variables transform non-linearly under GL(n,C), but linearly under its notable subgroups, the little group and the permutation group Sn. Using GL(n,C) covariant variables, we present a n...
متن کاملTree Scattering Amplitudes *
The spin-4/3 fractional superstring is characterized by a chiral algebra involving a spin-4/3 current on the world-sheet in addition to the energy-momentum tensor. These currents generate physical state conditions on the fractional superstring Fock space. Scattering amplitudes of these physical states are described which satisfy both spurious state decoupling and cyclic symmetry (duality). Exam...
