Maybe we really don't need supersymmetry.... Webb1 nov. 2024 · Understanding naturalness as the imposition that fine-tuning problems have to vanish, for instance, due to the existence of new particles, new models as those based in supersymmetry were built. In order to palliate the fine-tuning problem the Higgs sector of the standard model seems to suffer, new physics should have appeared already in the …
Is naturalness already hidden within the Standard Model?
Webb14 okt. 2015 · In the pure fundamental particles domain there is no naturalness; either naturalness does not exist or there is a need for a new physics or new particles. The `Astrophysical Naturalness' offers a third possibility: stars introduce the combinations of, or relations among, known fundamental quantities that lead to naturalness. Submission … Webb9 apr. 2024 · The unnatural mass of the Higgs boson might even be linked to the exceedingly small but non-zero value of the cosmological constant, which is responsible for the accelerating expansion of the universe. “This workshop provided us with a fantastic forum to bring a fresh perspective on naturalness problems, both in a variety of physical … economist\u0027s definition of investment

Also, the concept of “naturalness” in particle physics is not meant to criticize nature, but more as a heuristic to evaluate our current theories. 26. Reply. Share. Report Save Follow. Webb1 nov. 2024 · Naturalness (technical) • Applicable to quantum field theory • A dimensionless number much smaller than one must be protected by a symmetry or its smallness must be explained by some underlying physics. • Naturalness requires that numbers are not highly sensitive to the (presumed more fundamental) theory in the UV • … economics of living in a gaming lounge
