چکیده
In arXiv:2008.04330 it was shown that supertranslation and $\overline{SL(2,\mathbb C)}$ current algebra symmetries, corresponding to leading subleading soft graviton theorems, are enough determine the tree level MHV scattering amplitudes. this note we clarify role of subsubleading theorem in context.

Note on graviton MHV amplitudes
Two new formulas which express n-graviton MHV tree amplitudes in terms of sums of squares of n-gluon amplitudes are discussed. The first formula is derived from recursion relations. The second formula, simpler because it involves fewer permutations, is obtained from the variant of the Berends, Giele, Kuijf formula given in arXiv:0707.1035.
متن کاملInfinities within Graviton Scattering Amplitudes
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...
متن کاملOn Graviton 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/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 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...
متن کاملInfrared behavior of graviton-graviton scattering
The quantum effective theory of general relativity, independent of the eventual full theory at high energy, expresses graviton-graviton scattering at one loop order O ( E4 ) with only one parameter, Newton’s constant. Dunbar and Norridge have calculated the one loop amplitude using string based techniques. We complete the calculation by showing that the 1 d−4 divergence which remains in their r...
