Influence from the Future
C. D. Froggatt, H. B. Nielsen
We argue that some of the parameters in the laws of Nature would be well understood, under the assumption that there is an influence from the future as well as from the past, in th…
Dynamical determination of the top quark and Higgs masses in the Standard Model
C. D. Froggatt, H. B. Nielsen
We consider the application of the multiple point criticality principle to the pure Standard Model, with a desert up to the Planck scale. According to this principle, Nature should…
Fermion Masses and Anti-grand Unification
C. D. Froggatt, H. B. Nielsen, D. J. Smith
We present an extension of the Standard Model (SM) without supersymmetry, which we use to calculate order of magnitude values for the elements of the mass matrices in the SM. In ou…
Extending the Standard Model Using Charge Quantisation Rules
C. D. Froggatt, H. B. Nielsen, D. J. Smith
We examine extensions of the Standard Model (SM), basing our assumptions on what has already been observed; we don't consider anything fundamentally different, such as grand unific…
Electroweak Baryogenesis in a Supersymmetric Model
A. T. Davies, C. D. Froggatt, G. Jenkins +1
In the electroweak phase transition there arises the problem of baryon number washout by sphaleron transitions, which can be avoided if the phase transition is strongly enough firs…
Could there be a Fourth Generation of Quarks Without More Leptons?
C. D. Froggatt, H. B. Nielsen, D. J. Smith
We investigate the possibility of adding a fourth generation of quarks. We also extend the Standard Model gauge group by adding another SU(N) component. In order to cancel the cont…
The Top Quark and other Fermion Masses
Colin Froggatt
Recent developments on approaches to the quark lepton mass problem are reviewed. In particular we discuss dynamical calculations of the top quark mass at (a) the infrared quasifixe…
Electroweak Baryogenesis in the Next to Minimal Supersymmetric Model
A. T. Davies, C. D. Froggatt, R. G. Moorhouse
In the electroweak phase transition there arises the problem of baryon number washout by sphaleron transitions, which can be avoided if the phase transition is strongly enough firs…
