WebJan 20, 1986 · Abstract. Numerical evidence is found for the appearance of a massless vector state, the “photon”, in the broken phase of the lattice Georgi-Glashow model. Data is also presented for the lowest-lying scalar mass in the theory. Our simulations indicate that the transition between symmetric and broken phases is weakly first order for a wide ... WebEarly grand unification theories, such as the Georgi–Glashow model, which were the first consistent theories to suggest proton decay postulated that the proton's half-life would be at least 10^31 years. As further experiments and calculations were performed in the 1990s, it became clear that the proton half-life could not lie below 10^32 years. shang dynasty divination

Pedro D. Alvarez, Rafael A. Chavez, Jorge Zanelli. We present a scheme to construct grand unified models based on the superconformal algebra and the inclusion of matter fields in the adjoint representation of supersymmetry. As an illustration, we implemented the Georgi ... WebIn particle physics, the Georgi–Glashow model[1] is a particular grand unified theory proposed by Howard Georgi and Sheldon Glashow in 1974. In this model the standard model gauge groups SU × SU × U are combined into a single simple gauge group SU .
