The Quark Lepton Mass Problem and the Anti-Grand Unification Model
C. D. Froggatt
The fermion mass problem and the ideas of mass protection are briefly reviewed. The Fritzsch ansatz for the quark mass matrices and a recent variant, based on a lightest flavour mi…
Why do we have parity violation?
C. D. Froggatt, H. B. Nielsen
We discuss here two of the questions posed at the beginning of the Bled 1998 workshop: Why is the weak charge dependent on handedness? Why do we have parity violation in the Standa…
Masses and mixing angles and going beyond the Standard Model
C. D. Froggatt, H. B. Nielsen
The idea, following Michel and O'Raifeartaigh, of assigning meaning to the (gauge) \underline{group} and not only the Lie algebra for a Yang Mills theory is reviewed. Hints from th…
What comes beyond the standard model?
Norma Mankoc Borstnik, Holger Bech Nielsen, Colin Froggatt
The Proceedings collects the results of ten days of discussions on the open questions of the Standard electroweak model as well as the review of the introductory talks, connected w…
CP Violation in the Next to Minimal Supersymmetric Standard Model
A. T. Davies, C. D. Froggatt, A. Usai
We consider spontaneous CP violation in the Next to Minimal Supersymmetric Standard Model (NMSSM), without the usual discrete symmetry. CP violation can occur at tree level,…
