The Problem of Mass
C. D. Froggatt
The quark-lepton mass problem and the ideas of mass protection are reviewed. The Multiple Point Principle is introduced and used within the Standard Model to predict the top quark…
Hierarchy Problem and a new Bound State
C. D. Froggatt, H. B. Nielsen
Instead of solving the fine-tuning problems by some automatic method or by cancelling the quadratic divergencies in the hierarchy problem by a symmetry (such as SUSY), we rather pr…
Cosmological constant in SUGRA models and the multiple point principle
C. Froggatt, L. Laperashvili, R. Nevzorov +1
The tiny order of magnitude of the cosmological constant is sought to be explained in a model involving the following ingredients: supersymmetry breaking in N=1 supergravity and th…
Family Replicated Gauge Group Models
C. D. Froggatt, L. V. Laperashvili, H. B. Nielsen +1
Family Replicated Gauge Group models of the type SU(n)^N\times SU(m)^N, (SMG)^3 and (SMG\times U(1)_{B-L})^3 are reviewed, where SMG=SU(3)_{c}\times SU(2)_{L}\times U(1)_{Y} is the…
Trying to understand the Standard Model parameters
C. D. Froggatt, H. B. Nielsen
We stress the importance of the circa 20 parameters in the Standard Model, which are not fixed by the model but only determined experimentally, as a window to the physics beyond th…
The Origin of Mass
C. D. Froggatt
The quark-lepton mass problem and the ideas of mass protection are reviewed. The hierarchy problem and suggestions for its resolution, including Little Higgs models, are discussed.…
Supersymmetric Grand Unification with a Fourth Generation?
J. E. Dubicki, C. D. Froggatt
The possibility of incorporating a chiral fourth generation into a SUSY-GUT is investigated. Precision fits to electroweak observables require us to introduce light supersymmetric…
