چکیده
A bstract We provide a new efficient diagrammatic tool, in the context of scattering equations, for computation covariant D -dimensional tree-level n -point amplitudes with pairs spinning massive particles using compact exponential numerators. discuss how this framework allows non-integer spin extensions recurrence relations developed integer spin. Our results facilitate on-going program generating observables classical general relativity from on-shell tree through Kawai-Lewellen-Tye and generalized unitarity.

Gravitons scattering from classical matter
The low energy scattering of gravitons from a composite extended system, which is made of classical massive bodies, is considered; by using the Feynman rules of effective quantum gravity, the corresponding cross-section is computed to lowest order in powers of the gravitational coupling constant. For the gravitons scattering from a rotating planet or a star, it is shown that the classical limit...
متن کاملConsistent Massive Colored Gravitons
A short review of the problems with the action for massive gravitons is presented. We show that consistency problems could be resolved by employing spontaneous symmetry breaking to give masses to gravitons. The idea is then generalized by enlarging the SL(2,C) symmetry to SL(2N,C)× SL(2N,C) which is broken to SL(2,C) spontaneously through a non-linear realization. The requirement that the space...
متن کاملStability of Massive Cosmological Gravitons
We analyze the physics of massive spin 2 fields in (A)dS backgrounds and exhibit that: The theory is stable only for masses m2 ≥ 2Λ/3, where the conserved energy associated with the background timelike Killing vector is positive, while the instability for m2 < 2Λ/3 is traceable to the helicity 0 energy. The stable, unitary, partially massless theory at m2 = 2Λ/3 describes 4 propagating degrees ...
متن کاملNon-Pauli-Fierz massive gravitons.
We study general Lorentz invariant theories of massive gravitons. We show that, contrary to the standard lore, there exist consistent theories where the graviton mass term violates Pauli-Fierz structure. For theories where the graviton is a resonance, this does not imply the existence of a scalar ghost if the deviation from a Pauli-Fierz structure becomes sufficiently small at high energies. Th...
متن کاملGauge Model With Massive Gravitons
Gauge theory of gravity is formulated based on principle of local gauge invariance. Because the model has strict local gravitational gauge symmetry, gauge theory of gravity is a perturbatively renormalizable quantum model. However, in the original model, all gauge gravitons are massless. We want to ask that whether there exists massive gravitons in Nature? In this paper, we will propose a gauge...
