نویسندگان
چکیده
We summarize the status of theory resummed quantum gravity. In context Planck scale cosmology formulation Bonanno and Reuter, we review use our gravity approach to Einstein’s general relativity estimate value cosmological constant as ρΛ = (0.0024 eV)4. Constraints on susy GUT models that follow from closeness experiment are noted. Various consistency checks calculation discussed. particular, Heisenberg uncertainty principle remove a large part remaining in ρΛ.

Resummed Quantum Gravity
We present the current status of the a new approach to quantum general relativity based on the exact resummation of its perturbative series as that series was formulated by Feynman. We show that the resummed theory is UV finite and we present some phenomenological applications as well.
متن کاملPlanck Scale Remnants in Resummed Quantum Gravity †
We show that, in a new approach to quantum gravity in which its UV behavior is tamed by resummation of large IR effects, the final state of the Hawking radiation for an originally very massive black hole is a Planck scale remnant which is completely accessible to our universe. This remnant would be expected to decay into n-body final states, leading to Planck scale cosmic rays.
متن کاملMassive Elementary Particles and Black Holes in Resummed Quantum Gravity
We use exact results in a new approach to quantum gravity to show that the classical conclusion that a massive elementary point particle is a black hole is obviated by quantum loop effects. Further phenomenological implications are discussed.
متن کاملBlack Holes and Massive Elementary Particles in Resummed Quantum Gravity †
Einstein's general theory of relativity poses many problems to the quantum theory of point particle fields. Among them is the fate of a massive point particle. Since its rest mass exists entirely within its Schwarzschild radius, in the classical solutions of Einstein's theory, the respective system should be a black hole. We address this issue using exact results in a new approach to quantum gr...
متن کاملA Quasilocal Hamiltonian for Gravity with Classical and Quantum Applications
I modify the quasilocal energy formalism of Brown and York into a purely Hamiltonian form. As part of the reformulation, I remove their restriction that the time evolution of the boundary of the spacetime be orthogonal to the leaves of the time foliation. Thus the new formulation allows an arbitrary evolution of the boundary which physically corresponds to allowing general motions of the set of...
