WebSep 4, 1997 · The Higgs boson may serve as a portal to new physics beyond the standard model (BSM), which is implied by the theoretical naturalness or experimental anomalies. This review aims to briefly survey some typical Higgs-related BSM models. First, for the theories to solve the hierarchy problem, the two exemplary theories, the low energy … WebIn it is shown that it is possible to modify the standard theory by adding a scalar which possesses a discrete symmetry and to address the issue of the dark matter of the universe, within the frame work of singlet extended SM; the issue of dark matter has been studied in [6–13], while electroweak phase transition was studied in [14–23] and ...
