Infinities within Graviton Scattering Amplitudes
نویسندگان
چکیده
We present unitarity as a method for determining the infinities present in graviton scattering amplitudes. The infinities are a combination of IR and UV. By understanding the soft singularities we may extract the UV infinities and relate these to counter-terms in the effective action. As an demonstration of this method we rederive the UV infinities present at one-loop when gravity is coupled to matter. † [email protected] ‡ [email protected]

Tree Level Recursion Relations In General Relativity
Recently, tree-level recursion relations for scattering amplitudes of gluons in YangMills theory have been derived. In this note we propose a generalization of the recursion relations to tree-level scattering amplitudes of gravitons. We use the relations to derive new simple formulae for all amplitudes up to six gravitons. In particular, we present an explicit formula for the six graviton non-M...
متن کاملGraviton scattering amplitudes in M theory
We compute graviton scattering amplitudes in M theory using Feynman rules for a scalar particle coupled to gravity in eleven dimensions. The processes that we consider describe the single graviton exchange and the double graviton exchange, that in M~atrix! theory correspond to the v/r and v/r term, respectively. We argue that the v/r term appearing in M~atrix! theory at two loops can be obtaine...

We compute graviton scattering amplitudes in M-theory using Feynman rules for a scalar particle coupled to gravity in eleven dimensions. The processes that we consider describe the single graviton exchange and the double graviton exchange, that in M(atrix) theory correspond to the v/rand v/r-term respectively. We further show that the v/r-term appearing in M(atrix) theory at two-loops can be ob...
متن کاملRecovering Infinities in Graviton Scattering Amplitudes using Cutkosky rules
We use the Cutkosky rules as a tool for determining the infinities present in graviton scattering amplitudes. We are able to confirm theoretical derivations of counterterms in Einstein-Maxwell theory and to determine new results in the Dirac-Einstein counterLagrangian. † email: [email protected] One of the central issues in perturbative quantum gravity [1] and supergravity [2] is that of ...
متن کاملCalculation of Graviton Scattering Amplitudes using String-Based Methods
Techniques based upon the string organisation of amplitudes may be used to simplify field theory calculations. We apply these techniques to perturbative gravity and calculate all one-loop amplitudes for four-graviton scattering with arbitrary internal particle content. Decomposing the amplitudes into contributions arising from supersymmetric multiplets greatly simplifies these calculations. We ...
