Landscape Predictions for the Higgs Boson and Top Quark Masses
Brian Feldstein, Lawrence J. Hall, Taizan Watari
If the Standard Model is valid up to scales near the Planck mass, and if the cosmological constant and Higgs mass parameters scan on a landscape of vacua, it is well known that the…
A Stable Proton without R-Parity--Implications for the LSP--
Radu Tatar, Taizan Watari
The proton decays too rapidly in supersymmetric theories if a dimension-4 operator \bar{5}.10.\bar{5} exists in the superpotential. The conventional idea is to impose the R-parity…
Proton Decay, Yukawa Couplings and Underlying Gauge Symmetry in String Theory
Radu Tatar, Taizan Watari
In string theory, massless particles often originate from a symmetry breaking of a large gauge symmetry G to its subgroup H. The absence of dimension-4 proton decay in supersymmetr…
Taming the Runaway Problem of Inflationary Landscapes
Lawrence J. Hall, Taizan Watari, T. T. Yanagida
A wide variety of vacua, and their cosmological realization, may provide an explanation for the apparently anthropic choices of some parameters of particle physics and cosmology. I…
Big-Bang nucleosynthesis (Particle Data Group mini-review)
Brian Fields, Subir Sarkar
A critical review is given of the current status of cosmological nucleosynthesis. In the framework of the Standard Model with 3 types of relativistic neutrinos, the baryon-to-photo…
