Perturbative Quantization of Gravity Theories
نویسنده
چکیده
We discuss relations between gravity and gauge theory tree amplitudes that follow from string theory. Together with D-dimensional unitarity, these relations can be used to perturbatively quantize gravity theories, i.e. they contain the necessary information for calculating complete gravity S-matrices to any loop orders. This leads to a practical method for computing non-trivial gravity S-matrix elements by relating them to much simpler gauge theory ones. We also describe arguments that N = 8 D = 4 supergravity is less divergent in the ultraviolet than previously thought.

Perturbative Quantum Gravity and its Relation to Gauge Theory
In this review we describe a non-trivial relationship between perturbative gauge theory and gravity scattering amplitudes. At the semi-classical or tree-level, the scattering amplitudes of gravity theories in flat space can be expressed as a sum of products of well defined pieces of gauge theory amplitudes. These relationships were first discovered by Kawai, Lewellen, and Tye in the context of ...
متن کاملExact Path Integral Quantization of Generic 2-D Dilaton Gravity
Local path integral quantization of generic 2D dilaton gravity is considered. Locality means that we assume asymptotic fall off conditions for all fields. We demonstrate that in the absence of ‘matter’ fields to all orders of perturbation theory and for all 2D dilaton theories the quantum effective action coincides with the classical one. This resolves the apparent contradiction between the wel...
متن کامل2 the Classical Electromagnetic Field 3 2
A condensed introduction to quantum gauge theories is given in the perturbative S-matrix framework; path integral methods are used nowhere. This approach emphasizes the fact that it is not necessary to start from classical gauge theories which are then subject to quantization, but it is also possible to recover the classical group structure and coupling properties from purely quantum mechanical...
متن کاملPhase Transition in Quantum Gravity
A fundamental problem with attempting to quantize general relativity is its perturbative non-renormalizability. However, this fact does not rule out the possibility that non-perturbative effects can be computed, at least in some approximation. We outline a quantum field theory calculation, based on general relativity as the classical theory, which implies a phase transition in quantum gravity. ...
متن کاملThe future of spin networks
Since Roger Penrose rst introduced the notion of a spin network as a simple model of discrete quantum geometry, they have reappeared in quantum gauge theories, quantum gravity, topological quantum eld theory and conformal eld theory. The roles that spin networks play in these contexts are brie y described, with an emphasis on the question of the relationships among them. It is also argued that ...
