Grand Unification with Anomalous U(1) Symmetry
Nobuhiro Maekawa
In this talk, we introduce a new scenario of grand unified theory (GUT) with anomalous gauge symmetry. Since generic interactions (including non-renormalizable interaction…
A Road to the Standard Grand Unified Theory
Nobuhiro Maekawa
In this talk, we propose a GUT scenario in which doublet-triplet splitting is naturally realized in SO(10) unification using the Dimopoulos-Wilczek mechanism and the realistic mass…
Vacuum selection by recollapsing
Nobuhiro Maekawa
We discuss the possibility that the vacuum is dynamically determined in the history of the universe. The point is that some of the bubbles with a certain vacuum shrink by the evolu…
Search for Dynamical Symmetry Breaking Physics by Using Top Quark
T. Asaka, N. Maekawa, T. Moroi +2
We report first results from the investigation on probing dynamical mechanism of the electroweak symmetry breaking using top quark. We consider the case where the top mass originat…
