Higgs forcing Occam's return (Introduction)

Simple is better than the naturalness theory (which requires highly complex adjustments) and that is what the small mass of Higgs is suggesting:-A concluding paragraph:-"it is still possible that nature is
atural", in the sense of 't Hooft. Future runs of the LHC might provide evidence for supersymmetry, warped extra dimensions, or some variant of technicolor. But the current experimental situation raises the unsettling possibility that naturalness may not be a good guiding principle. Indeed, naturalness is in tension with another principle: simplicity. Simplicity has a technical meaning: the simplest theory is the one with the smallest number of degrees of freedom consistent with known facts.Contrast, for example, the minimal Standard Model, with its single Higgs doublet, with supersymmetric theories, with their many additional elds and couplings. So far, the experimental evidence suggests that simplicity is winning. The observed Higgs mass is in tension with expectations from supersymmetric theories, but also technicolor and other
proposals"-http://arxiv.org/pdf/1501.01035v1.pdf
