The New Minimal Standard Model
... In this letter, we advocate a different and conservative approach to physics beyond the MSM. We include the minimal number of new degrees of freedom to accommodate convincing (e.g., > 5σ) evidence for physics beyond the MSM. We do not pay attention to aesthetic problems, such as fine-tuning, the hie ...

It is important to notice that, even without new physics, S, T and U provide a convenient means for approximating deviations from our assumed mt = 175 GeV and mH = 300 GeV values. (However, since the main mH depe ...
