We expect the unknown structure of the mysterious symmetry breaking of the Standard Model to be revealed. The energy scales now probed by the Tevatron, of order hundreds of GeV, will soon be subsumed by the LHC and extended up to a few TeV. We are thus entering a dramatic and important more ยป time in the quest to understand the fundamental laws of nature and their role in shaping the universe. This will represent a revolution in our understanding of nature, and will either bring us closer to an understanding of all phenomena, through existing ideas such as supersymmetry to superstrings, or will cause us to scramble to find new ideas and a new sense of direction. These phenomena will be revealed through experiment with high energy particle accelerators, mainly the LHC. Within the next ten years the Standard Model will likely have to be modified to encompass a wide range of newly discovered phenomena, new elementary particles, new symmetries, and new dynamics. All dimensionless input parameters are of order 1 and do not require fine-tuning. Excellent 4 to 6 parameter fits to the 10 observables in the quark sector are obtained. ![]() There is an indication that large values of is a characteristic mass scale common to all form factors) simple analytical expressions for the mass matrices. We illustrate these properties with a simple toy model and give examples where all mass and mixing parameters are in agreement with available experimental information. Then, allowing the shape of the form factors at the coupling to these heavy fermions to be slightly dependent on generation and flavor indices will produce both mass hierarchies and flavor mixing of the type observed. An essential further assumption is that the intermediate heavy fermions and emitted bosons are common to quarks or leptons belonging to all generations. The quarks and leptons are assumed to acquire their masses by coupling to heavy fermions through emission and reabsorption of bosonic quanta (bound states or gauge bosons). ![]() We propose a general dynamical scheme capable of explaining the main properties of the observed spectrum.
