Webb22 juli 2024 · As observed in Figure 5, the numerical results from the present cases agree well with the theoretical results from all of the cases simulated under different gravity fields. However, upon close examination of the wave crest, the wave traveling distance and the trailing oscillatory waves, some discrepancies are detected between the numerical … Webb1 apr. 2016 · We derive new constraints on massive gravity from unitarity and analyticity of scattering amplitudes. Our results apply to a general effective theory defined by Einstein gravity plus the leading soft diffeomorphism-breaking corrections. We calculate scattering amplitudes for all combinations of tensor, vector, and scalar polarizations.
Gravitational theory and other aspects of physical theory
Webb1 okt. 2024 · In contrast to the standard theory of mass-varying massive gravity where the graviton mass asymptotically approaches zero at late times, hence making the contribution of massive gravity to the late-time cosmic expansion minimum, the MTMVMG can provide good descriptions both in the massless and massive sectors. WebbThis thesis is dedicated to the study of theories of massive gravity. The formulation of higher spin gauge field theories, along with a Chern-Simons (CS) like term for fields of higher spins is presented. Through this setup, general features of theories describing massless/massive fields of higher spin in arbitrary dimensions is discussed. In 2+1 … c# source generators .net 6
