Toward Quantum Gravity II: Quantum Tests
Abstract
This study toward quantum gravity (QG) introduces an SU(N) gauge theory with the \Theta vacuum term for gravitational interactions, which leads to a group SU(2)_L x U(1)_Y x SU(3)_C for weak and strong interactions through dynamical spontaneous symmetry breaking (DSSB). Newton gravitation constant G_N and the effective cosmological constant are realized as the effective coupling constant and the effective vacuum energy, respectively, due to massive gauge bosons. A gauge theory relevant for the nonzero gauge bosons, 10^{12} GeV, and the massless gauge boson (photon) is predicted as a new dynamics for the universe expansion: this is supported by the repulsive force, indicated in BUMERANG98 and MAXIMA1 experiments, and cosmic microwave background radiation. Under the constraint of the flat universe, \Omega = 1  10^{61}, the large cosmological constant in the early universe becomes the source of the exponential expansion in 10^{30} order as expected in the inflation theory, nearly massless gauge bosons are regarded as strongly interacting mediators of dark matter, and the baryon asymmetry is related to the DSSB mechanism.
